Privacy Policy

Kin Album is a private, end-to-end encrypted family photo album, operated by Cobblestone, LLC (“Kin Album,” “we”). This policy says what we collect, what we can and cannot see, and the controls you keep. The short version: your photos are encrypted so that we cannot look at them (with two exceptions, described below: the small preview copies made while your album sends photos in emails, and an invitation emailed from the iPhone app), we show no ads, we sell nothing about you, your album’s admins can export the whole album at any time, and you can delete anything you’ve posted, or your account.

Our promises

Three things will not change:

These are promises, not settings. We will never change them unless we first ask you and you agree, and anyone who takes over Kin Album has to keep them too.

What we collect

What we can and cannot see

End-to-end encryption is always on — it is not a setting. Encryption keys live on your family’s devices, so we cannot see your photos or videos — with the two exceptions below. We can see the metadata required to run the service: who is in a family, captions and comments, child profile names and birthdates, timestamps, and file sizes. The first exception’s scope is wider than it sounds, so here it is plainly: if an album admin turns on “Send photos in their emails” for even one person, then from that moment small photo renditions are prepared outside encryption for every photo posted to that album, by every member — not only for the photos that person is sent. Those renditions are stored with us, beside the encrypted originals, for about 30 days after each photo is posted, and they are not end-to-end encrypted while they exist. Full-quality originals stay encrypted throughout. Turning the setting off again stops new renditions being made and deletes the ones already made, within a day.

The second is an emailed invitation. When you invite someone by email from the iPhone app, the link in that email carries the secret that lets their device join the album’s encryption: it unlocks a locked copy of the album key that we keep for that invitation. The link passes through our server and our email provider on its way, and our email provider keeps a copy of each email it sends for 30 days, and up to 7 days more in its backups — so until the invitation ends, we could in principle use that link to unlock the album. Like anything sent by email, it is also only as private as the recipient’s inbox. That is why an invitation lasts only 14 days, why each of its links works only for the address it was sent to, and why we delete the locked copy of the album key the moment an invitation is withdrawn and within an hour of it expiring. Once that copy is gone — and has rotated out of our encrypted database backups, within 14 days — the copy at our email provider can no longer open anything. A link does not stop working when it is first used: until it expires, it keeps working for the person it was sent to, which is how they open the album on a second phone, tablet or browser. Withdrawing an invitation that hasn’t been used stops all of its links at once, and removing someone from the album stops them working for that person. Replies to an emailed invitation go to the email address of the person who sent it, so the person invited can see that address; when we can’t use it — for example, an address from Apple’s Hide My Email — the invitation says replies aren’t delivered.

Separately, anything you choose to attach when you contact us from the app reaches our support team as it is; see “Messages to support” above.

How we use information

To provide Kin Album: storing and syncing your album, delivering invitations, notifications and email updates, taking payments, answering you when you write to us, keeping the service secure and free of abuse, and finding and fixing problems. We also use the counts described under “Feature usage” to make Kin Album easier to use. We don’t show ads, we never sell personal information, and we don’t use your family’s content to train AI (see “Our promises”). We do measure whether our own ads work: if you installed Kin Album from an ad, Apple’s ad measurement tells that ad network — without identifying you — whether the install led to a monthly or yearly subscription. Apple sends us a copy of the same report.

To apply the free plan’s storage limit and the daily limit on how much any album can add, we use the size of each encrypted photo and video file, which we record when it is uploaded. A size is all it tells us: the file itself stays encrypted, and its size says nothing about what is in it.

We use a gift-time purchase to add the time to the album, to take it off again if Apple refunds it, and to show the person who bought it their own purchases. The family is never shown who gave gift time or how much it cost. An album’s admins can see the date the album is paid through and how much gift time is waiting; other members can’t.

If you pay for another family’s album, we use that record to apply your subscription to the album the family starts, to show you your own links and the albums your subscription pays for, and, if your subscription stops paying for that album, to tell you by email and in the app, with how to cancel it. The album’s admins can see who pays for the album and what it costs; other members aren’t shown it. An admin who goes to remove you is also told that you pay for it.

We use a website purchase to give the album its paid time or gift time, to stop a subscription renewing when the album no longer needs it, to refund unused gift time to your card when an album is deleted, to refund unused time to your card if Kin Album shuts down, to take time off the album if Stripe refunds a purchase, and to show you your own purchases. To take the payment, we send Stripe the email address on your account and a reference number for the purchase. We send it nothing about your album: not its name, its photos or videos, or anyone in it. In the family, only the album’s admins can see who paid and how much it costs.

Notifications

If you turn on notifications, we send you alerts when someone posts a memory or comments, and, if you are an album admin, about things like a screenshot or a report — in the iPhone app through Apple’s notification service, in the Android app through Google’s Firebase Cloud Messaging, and in a web browser through your browser’s push service (Google, Mozilla or Apple, depending on the browser). Those alerts are written by our servers and contain only a first name and a short phrase, such as “Maya added a new memory,” and the reference numbers the app needs to open the right album or memory. They never contain a photo, a caption, or the text of a comment, because a notification travels outside the encryption that protects your album. Browser notifications are additionally encrypted so the push service relaying them cannot read them. In the Android app, Firebase is switched on only after you say yes to notifications, and we use it for nothing else: no Google Analytics, no crash reports. It gives your phone an address for alerts, which we keep with your account, together with your notification settings and the app’s version. We delete it when you sign out on that phone, when you delete your account, or when Google tells us the app is no longer on the phone. You can turn notifications off at any time in your device or browser settings, and email updates keep working either way.

Email from us

Most of our email is part of the service: invitations, your album’s updates, sign-in and security messages, payment reminders, and notices about your account or album.

We send news about Kin Album, such as new features, tips or offers, only to people who ask for it, for example by ticking a box that asks. Every one of those emails has a one-click unsubscribe link, and unsubscribing never affects your album or its emails. Today we send no such news.

Crash reports

If the app crashes or freezes, your device may send us an anonymized technical report (using Apple’s MetricKit) so we can find and fix the problem. These reports describe the app’s behavior — where it was in the code when it failed — never your photos, captions, comments, or anything you wrote. They are sent only to our own systems, never to a third-party crash service, and are not linked to your identity. Once a day, the iPhone app may also send anonymous statistics about how it performed (for example how long it took to open, whether it was slow to respond, and how much memory, battery and data it used), under the same rules. The Android app sends no crash reports or performance statistics.

Service providers

Like every online service, we rely on other companies to run parts of Kin Album, each bound by their own data-processing terms. We use them in these categories, and these are the ones we use today:

If we add or replace a provider within one of these categories, we update this list. That is a routine update. A new kind of provider, or giving a provider something new about you, is a change we tell you about in the Kin Album app first (see “Changes to this policy”).

None of them can decrypt your photos or videos. The email preview copies described above are not encrypted: Cloudflare stores them, and Resend delivers them in those emails. Nor is a photo or video you attach to a message to support: Resend delivers it to our support inbox.

When you pay on kinalbum.com, Stripe takes the payment, through its payment service Link. It is more than a provider that works for us: it is an independent company, Link is the seller of record for those purchases, and Stripe handles sales tax, fraud checks and disputes. When you pay, you leave our website for a page Stripe hosts, and Stripe’s own privacy notice applies to the payment details you give it there. Stripe never receives your photos, videos, captions or comments, or your album’s name.

When the law or someone’s safety requires it

Beyond the uses above, we share information only:

We share only what’s needed. Photos and videos stay end-to-end encrypted, so we can’t hand over what we can’t open, apart from the two exceptions under “What we can and cannot see”. Anyone, with or without an account, can tell us about something that may be illegal or break our Terms at kinalbum.com/report.

Where your information is stored

Kin Album is run from the United States, and your account, albums and photos are stored in North America. If you use Kin Album from another country, your information is sent to North America to be stored, and some of our providers may also handle it in other countries. Where the law of your country requires it, as in the UK and the EU, those transfers are protected by our providers’ standard contractual clauses, or by the EU-US Data Privacy Framework and its UK Extension where a provider takes part.

Retention and deletion

How long we keep things

Your content stays as long as your album does. If your subscription lapses, your albums move to the free plan — nothing is deleted for two years. After that, an album without a subscription is deleted if its owner’s albums without one hold more than the free plan’s storage, or if no member has opened it for two years, always after 90 days’ notice by email to its admins and in the app, with a free export (the Terms of Service give the details). To apply that rule we keep, for each album, the day a member last opened it and the day its subscription stopped, and a record of each notice we sent, which we keep after the album is deleted as proof the notice was given (it holds no photo, caption, name or email address); the album itself is purged like any other deleted album. A record of each gift-time purchase is kept after its album is deleted, so the person who bought it can still see it — with any unused whole months. For gift time bought in the iPhone app, they can ask Apple to refund those on Apple’s refund page; for gift time bought on the website, we refund them to the card ourselves, if the purchase is still inside Stripe’s refund window. If that person closes their account, the record no longer says who bought it. Deleting your account, or an album you own (both are in Settings), starts a 30-day grace window during which you can change your mind. When it ends, a deleted album is permanently purged from our live systems, with every photo, video, caption and comment in it, unless the law requires us to keep something for longer. A deleted account’s sign-in, name, email address or phone number, and the comments and hearts it left are purged, and so is any album only that person was in. Photos and videos it posted to an album other people are still in stay with that album, with everyone’s comments and hearts, credited to “a former member” — anyone can delete a memory they posted before closing their account. Where an album’s invitations or activity still show that account’s address or number, it is replaced with “a deleted account”. Old profile pictures — ones that were replaced, or whose profile, album or account was deleted — are left in our storage only as scrambled files no one can open, including us: the key that unlocked each one is deleted. Residual copies in our encrypted database backups rotate out within 14 days. Deleted photos and videos are removed from our backups within 30 days. Album admins can export a complete archive at any time, from the iPhone app or on kinalbum.com. On kinalbum.com the copy is decrypted in your web browser: our servers send it only the encrypted files, as they do to the app. Anyone else can ask their album’s admin for a copy, or write to privacy@kinalbum.com for the personal information we hold about them.

If a family sends you photos by email

A family admin can add you as an email recipient: new photos arrive in your inbox, and you never need an account. Once an album is a few months old you may also get an occasional “one year ago” note naming a moment from that week — no photograph, just the caption and who shared it, with a link to the album. A family admin can switch those off for the whole album. For that to work we hold your email address, the name the admin typed for you, and when we last sent you each kind of email — nothing else, and never a password, because you don’t have one. The photos in those emails are preview-size copies; the originals stay in the family’s end-to-end encrypted album. Every email has an unsubscribe link. One press stops every email from that album straight away, and the person who added you can see that you opted out. On the same page you can then delete your address from that album’s email list yourself: we erase your email address and the name the admin typed for you from that list, and it shows only “Address deleted”. Any invitation from that album to that address that you hadn’t accepted yet is withdrawn too. To stop the album quietly adding you back, we keep a fingerprint of your address — made with a secret key that is created inside our database and never leaves it, except inside our encrypted backups of that database — and the date you deleted it. The fingerprint is not your address. Because we hold its key, we could check whether a given address matches it, and that check is its only use: if an admin types your address into that album again, the app tells them you asked to be removed and adds you back only if they confirm you asked. If you mark our mail as spam, we stop permanently — even after you delete your address. Copies in our encrypted database backups rotate out within 14 days, and our email provider’s records of emails already sent to you follow its own retention.

If you joined the waitlist

Before the app was in the App Store you could leave an email address to be told when it launched. We hold that address, the date you gave it, and a short label saying which page it came from — nothing else, and no account, because you don’t have one. It is used for exactly one message: that Kin Album is live. It is not a newsletter, we never sell or rent the list, and it is not connected to any album. If you’d also like news about Kin Album after that, we’ll ask you, and you’ll get it only if you say yes. Nothing about the waitlist is shared with anyone. We don’t tell any advertising platform that you signed up or how you found us, even if you arrived by clicking an advertisement, and no advertising company’s code runs on this website or sets a cookie for it. To stop the form being flooded, we count signup attempts for each email address, and for each internet address they come from, for an hour. The count is stored under a scrambled value made with the day’s random key described under “Technical basics” above — once that key is deleted, and has rotated out of our encrypted database backups within 14 days, no one, including us, can tell which address a count belonged to — and the count itself is deleted within three days. Write to privacy@kinalbum.com and we will delete your address the same way we would delete an account.

If you’re in the UK, the European Economic Area or Switzerland, or we can’t tell where you are, we email you a link to confirm your address, and you join the list only when you use it. While we wait, we keep your address, the same short label and a scrambled form of the link’s code, for up to 7 days; the link works once. If you don’t confirm, all of it is deleted within a day after the link expires. To stop that form sending you too many emails, we count confirmation requests for each address for a day, stored the same scrambled way as the signup count above. To decide whether this applies, our website uses the country your internet address points to, as our hosting provider tells us for each request. We don’t store it.

Do Not Track and Global Privacy Control

No advertising or analytics company’s code runs on our website, and no other company collects information there about what you do across other sites. The one outside company whose code does run in your browser there is Sentry, our error-monitoring provider: it can send us a report when something breaks, a note of whether each page opened without an error, and page-load timings for a small sample of visits — with personal identifiers turned off, and only so we can find and fix problems. Our website makes no report to any advertising platform. If your browser sends a Global Privacy Control signal, we treat it as a request not to share. We don’t otherwise change anything in response to “Do Not Track” signals, because our website does no cross-site tracking for them to switch off.

Children

Kin Album accounts are for adults 18 and over. When we ask you to confirm you’re 18 or older (on iPhones that offer it, we ask Apple), we keep only that yes and when it was given, never your age or age range. We do not knowingly collect personal information from children; photos and profile details about children are provided by their own parents or guardians, who control exactly who can see them and can delete them at any time. If you believe someone under 18 has an account, contact us and we will remove it.

How to see, export or delete your data

To get a copy of your album, an album admin can save one at any time: in the iPhone app, go to Settings → Export; on kinalbum.com, go to Settings → Save a copy of your album. If you’re not an admin, ask one. To close your account, go to Settings → Account in the app (on kinalbum.com, Settings → Your account), or to kinalbum.com/delete-account. For anything else, such as a copy of the personal information we hold about you, a correction, or a question about how we use it, write to privacy@kinalbum.com. You don’t need an account to write to us.

Your rights

Regardless of where you live, you can access, correct, or delete your information with the tools built into Settings, album admins can export their album from Settings in the iPhone app or on kinalbum.com, and we honor the same rights by email at privacy@kinalbum.com, including a copy of the personal information we hold about you. Residents of California, the EU/EEA, and similar jurisdictions may have additional statutory rights; we apply the built-in controls above to everyone rather than gating them by geography. If you’re in the UK or the EU, the next section explains how these rights apply to you.

If you’re in the UK or the EU

Kin Album is for families in the United States, but a relative in the UK or the EU may be invited to an album or added to its emails. If you are in the UK, the EU or the European Economic Area, this section applies to you.

Who is responsible. Cobblestone, LLC, 8735 Dunwoody Pl, Ste N, Atlanta, GA 30350-2995, USA, is responsible for your information. We have no office in the UK or the EU. To reach us about your information, write to privacy@kinalbum.com or to that address. We answer within one month.

Why we may use your information.

Your rights. You can ask for a copy of your information, ask us to correct it or delete it, ask for it in a form you can take elsewhere, ask us to limit how we use it, and object to uses based on our legitimate interests. You can withdraw consent at any time. Most of this is built into Settings; for the rest, write to privacy@kinalbum.com. We don’t make decisions about you by automated means that have legal or similarly significant effects.

Complaints. If you’re unhappy with how we’ve handled your information, please tell us first. You can also complain to the Information Commissioner’s Office in the UK, or to the data-protection authority where you live or work in the EU.

Transfers. Your information is stored in North America and handled by providers mainly in the United States. “Where your information is stored” explains how those transfers are protected.

Security

End-to-end encryption is the core of Kin Album’s design: what we store of your full-quality photos and videos is encrypted, and only your family’s devices can open it. The one exception is the email preview copies described under “What we can and cannot see”: in an album that uses them, the preview-size copies of photos posted in about the last 30 days are stored without end-to-end encryption. Account details, captions, and comments are not end-to-end encrypted (see “What we can and cannot see”); they are protected by industry-standard encryption in transit and at rest. If an incident affects your personal information, we will notify affected families by email promptly — within any legally required deadline, and no later than 30 days after we confirm it — with what happened and what we did.

If Kin Album changes hands

We don’t sell personal information. Apart from our service providers and the legal and safety reasons described above, we will transfer it to another company only as part of a transfer of Kin Album itself: a merger, an acquisition, a sale of the service, or a bankruptcy. Any company that takes over must agree to honor this policy, including “Our promises”, for the information we already hold, and may not use that information in a materially different way unless it first asks you and you agree. Full-quality photos and videos stay encrypted with keys held on your family’s devices, so a company that took over could no more open them than we can. The exceptions are the two described under “What we can and cannot see” — the small preview copies made while an album sends photos in emails, and an invitation emailed from the iPhone app, whose link carries the album’s secret through our servers until the invitation ends — and a company that took over would hold those under this policy, as we do. If Kin Album shuts down instead, we delete what remains after the shutdown date, unless the law requires us to keep something for longer: it is purged from our live systems, and copies in our encrypted database backups rotate out within 14 days.

Changes to this policy

This policy is effective from the date at the top of this page. When we change it, we update that date, and we keep every earlier version.

If a change is material, we also tell you in the Kin Album app before it applies, with a short note saying what changed. A change is material if it changes what we collect, how we use or share information, or what we can see, or if it takes away a choice or protection you have. If it takes something away, the note comes at least 30 days before the change applies. If a change affects people who receive album emails without an account, the next album email they receive will say so.

Some updates are routine and apply when we post them: adding or replacing a provider within a category listed under “Service providers”, adding another daily count that names no one, clearer wording, or describing a new feature that works within what this policy already says. Switching on something this policy already describes is not a change to the policy. Changing anything under “Our promises” always needs your agreement first.

We will not use information we have already collected in a materially different way from what this policy said when we collected it, unless we first ask you and you agree. If you don’t agree, that information stays under the policy it was collected under.

A change applies only from the day it applies. If you don’t want to continue under a change, you can stop using Kin Album and delete your account before it applies; if you are an album admin, export your album first. Apart from the ask-first promise above, continuing to use Kin Album once a change applies means you accept it. No change to this policy deletes photos or videos without first giving your album’s admins a chance to download them.
