Clann vs Ente Photos: The Most Private Way to Share Family Photos
Ente Photos is one of the few photo apps that takes privacy as seriously as Clann does, and it deserves its reputation. But the two apps answer different questions. Ente answers "where do I keep my own photo library?" Clann answers "where does my family share photos with each other?" If the second question is the one you are asking - a private space for a child's photos that grandparents can actually follow - Clann is built for it and Ente is not. Here is the detailed comparison, checked against both companies' own documentation.
One Is a Photo Library. One Is a Family.
Clann: A private, invite-only family group with one shared timeline. Everyone you invite sees it, adds to it, and comments on it. Grandparents open a link in a browser and follow along without installing anything, encrypted groups included. This is the entire product.
Ente Photos: An encrypted replacement for Google Photos - it holds your own camera roll. Sharing exists as albums you share out and links you generate, but there is no shared family space, and Ente's own documentation is explicit that even on a family plan, members cannot see each other's files unless something is deliberately shared.
If what you want is a private family feed, that difference decides it. In Ente you maintain an album and send it out. In Clann the family is already there.
Location Data: Clann Deletes It, Ente Encrypts It
Clann: In an end-to-end encrypted family group, EXIF and GPS data are stripped on your phone before encryption and are never uploaded at all. The coordinates of your home, attached by your camera to every photo of your child in the garden, do not leave the device. This is stated in Clann's published protocol specification, not just in marketing copy.
Ente Photos: Encrypts metadata rather than removing it - EXIF creation time, location and description are all end-to-end encrypted, so Ente cannot read them. That is genuinely strong, and stronger than Clann on the metadata Clann keeps.
The distinction worth understanding: encrypted data still exists and can be decrypted by anyone holding a key. Deleted data cannot. For the single most sensitive field on a family photo - where your child was standing - Clann's answer is to destroy it before upload.
What Each Company Can Actually See
Clann: Cannot see your photos or videos. They are encrypted on the sender's device with AES-256-GCM under a separate key per file, and the keys live only on family members' devices. Not covered by the encryption: captions, comments, group and album names, and the fact that a file exists, who uploaded it and when. Clann states this plainly on its encryption page rather than burying it.
Ente Photos: Cannot see your photos, videos, or their metadata. Ente's coverage is broader on paper, and that is a real advantage.
In practice, the gap is narrower than it looks for a family app. Ente has no comments or reactions to encrypt - its documentation lists them as coming soon - so the captions and conversation Clann cannot encrypt are features Ente does not have at all. Both companies are blind to the photos themselves, which is what actually matters when the concern is a provider mining a child's face.
The Encryption, Specifically
Clann: Every photo and video is encrypted on the sender's device before it is uploaded, with AES-256-GCM in chunks, under a data key generated fresh for that one file. That file key is wrapped to the family's group key, and the group key is sealed to each member's device using X25519 - so it travels to people, never to Clann. Devices hold Ed25519 identities and sign for one another, which means a new phone gets in because a family member's device approved it, not because a server said so.
Group keys are versioned by epoch. Remove someone from the family and the next epoch is minted without them: they keep whatever they could already read, and are cryptographically shut out of everything uploaded afterwards. If you lose a device, any other family member's device can let you back in, and a 12-word recovery phrase works when nobody else is available - Clann cannot restore your access, because Clann never had the key.
Ente Photos: XChaCha20 and XSalsa20 with Poly1305, keys derived with Argon2id, covering file contents and all metadata. Different primitives, comparable strength, and broader coverage than Clann's.
The point of listing Clann's is that they are listed. The normative protocol specification names every algorithm, every key in the hierarchy, the threats it defends against and the ones it does not - which is the standard Ente set, and the standard any app claiming end-to-end encryption should be held to.
Controls Over What Other People Can Do
Clann: This is where Clann is well ahead. Clann blocks screenshots and can notify owners and admins when someone attempts one. Group admins control whether members can download photos at all, whether viewers can upload, and whether comments are on. Admins approve every join request before anyone gets access, and members join with a short family code rather than a forwarded link.
Ente Photos: Viewer, collaborator and admin roles on shared albums, and public links that can carry a password, an expiry date, a device limit and a downloads toggle - all useful. But there is no way to stop a person you shared with from screenshotting, and no notification when they do. Ente's screenshot-related setting protects your own device from someone picking up your phone; it is not a control you apply to other people.
For photos of children shared with a wider family, "who can take a copy of this out of the app" is the control that matters most, and Clann is the only one of the two that answers it.
Comments, Reactions and the Point of Family Sharing
Clann: Comments are built in, and admins can switch them off for the whole group. The grandparent who comments on every single photo is not an edge case - she is the reason the app exists.
Ente Photos: Ente's collaboration documentation lists "comment and react" as coming soon, so as of August 2026 a shared album is somewhere to look at photos, not somewhere to talk about them. Entirely reasonable for a backup product.
Watching a Child Grow Up
Clann: A chronological timeline with age tracking, so every photo sits at the age your child actually was. Child profiles when there is more than one, memory books and custom albums you build from the photos worth keeping, favourites, and search by people, places, events and dates. Separate groups for each side of the family, with one-tap sharing to several at once.
Ente Photos: Curated memories, on-device face detection and grouping, on-device natural language search, a map view, hidden photos and legacy contacts. A strong feature set for a personal archive - none of it organised around a child, and none of it shared with your family by default.
Storage and Cost
Clann: Free to download with a 7-day free trial, then one subscription with unlimited photo and video storage. No tier to choose, no upload cap, and nobody in the family rationing video or deciding what to delete.
Ente Photos: 10GB free forever, then metered tiers. As of August 2026 the yearly plans are 50GB at $2.49/month ($29.88/year), 200GB at $4.99/month ($59.88/year), 1TB at $9.99/month ($119.88/year) and 2TB at $19.99/month ($239.88/year), priced the same worldwide, with up to 6 people able to share one plan's storage. Exceed your tier and Ente stops backing up new files until you upgrade or delete something.
Ente's free tier is a real advantage if you share very little. Past that, a family that shoots video will meet its storage ceiling on Ente and never meet one on Clann.
Verifying the Claims, Rather Than Believing Them
Clann: The cryptographic implementation and the normative protocol specification are published at github.com/ClannApp/clann-e2ee - every algorithm, every key in the hierarchy, the threat model, and a full account of what the encryption does not cover. The CLN1 format is pinned by test vectors generated by a second, independently written implementation, which is a stronger check on a file format than a round-trip test. And there is a browser demonstration running that exact format, so you can encrypt and decrypt a file yourself instead of taking the claim on trust.
Ente Photos: Two published third-party audits - Cure53 with Symbolic Software on the cryptography and clients in 2023, and a CERN-sponsored Cure53 audit of the server and infrastructure in 2025 - plus the entire stack published under AGPL-3.0 and the option to self-host it on your own hardware. If a formal audit report and fully open-source software are what you want on file, that is Ente's ground and it is worth choosing it for. Clann publishes its encryption, not its app: the client and server are closed and cannot be self-hosted.
Check the Claim Yourself, Right Here
You do not have to take any of this on trust. The tool below runs the exact CLN1 file format the Clann app writes: pick a photo, encrypt it in your browser, look at the ciphertext, then decrypt it back. Nothing is uploaded and nothing leaves this page - it is the published implementation running in front of you.
Pick a photo and watch it get locked
It never leaves this page — the locking happens right here in your browser, using the same encryption the Clann app uses on your phone.
No photo yet
On your phone
The photo is locked here, before anything is uploaded.

This page imports @clann/e2ee, the open-source package our app’s encryption is built on, so the file produced above is a real CLN1 envelope: a 32-byte header followed by the photo sealed in chunks with AES-256-GCM in the OAE2 STREAM construction — a counter nonce per chunk with the final one flagged, and the header used as authenticated data so it cannot be edited independently of the body. That is why editing the label or shuffling the pieces breaks the file.

So Which One Should a Family Choose?
If the question is "what is the most private way for my family to share photos of our children", Clann is the better answer. Every photo and video is encrypted on the sender's phone under a key Clann never holds, new family groups get that by default, location data is destroyed rather than stored, and it is the only one of the two that can stop a relative screenshotting your child's photo or walking into the group without an admin approving them.
When Ente Is the Right Choice
Ente Photos is a genuinely excellent product and for several jobs it is plainly the better pick. Choose Ente if:
- You want to replace Google Photos or iCloud for your own camera roll. Clann is a family sharing app, not a phone backup.
- You want a formal third-party audit report on file - Ente has two published Cure53 audits, one of them CERN-sponsored.
- You want fully open-source software you can inspect, fork or self-host on your own hardware.
- You need desktop apps or a command line tool, or you are backing up from Linux.
- You want to spend nothing - Ente's 10GB free tier is permanent, while Clann is a subscription after a 7-day trial.
Using both is a perfectly good answer
These apps do different jobs, and plenty of privacy-conscious families run both. Ente holds the encrypted archive of everything you have ever shot. Clann is where the handful of photos each week worth sharing go, so the family sees them, replies to them, and nobody has to be talked into installing anything.
Frequently Asked Questions: Clann vs Ente Photos
For sharing photos with family, Clann is the strongest option: photos and videos are end-to-end encrypted on your device by default in new family groups, EXIF and GPS location data are stripped on the phone and never uploaded, screenshots are blocked with admin notifications, admins approve every person who joins, and there are no ads and no AI training on your photos. Ente Photos is the strongest option for privately backing up your own photo library - its encryption additionally covers file metadata and it has two published third-party audits - but it has no shared family feed, no comments or reactions, and sells storage in tiers. Proton Drive is a reasonable choice if you already pay for Proton, and Apple's iCloud Shared Photo Library only works if every participant is on Apple devices with Advanced Data Protection enabled. Apps that are only "invite-only" or "private", such as FamilyAlbum, do not offer end-to-end encryption at all.
Very few. As of August 2026 the two family photo apps with genuine end-to-end encryption are Clann - photos and videos encrypted on the device, on by default for new family groups, with EXIF and GPS stripped before upload - and Ente Photos, which encrypts file contents and metadata but is a personal library rather than a shared family space. Proton Drive is end-to-end encrypted but is a general file drive, not a family photo app. Apple's iCloud Shared Photo Library is end-to-end encrypted only when every participant has Advanced Data Protection switched on, and everyone must be on Apple devices. FamilyAlbum, Tinybeans, Google Photos, Amazon Photos and Apple Shared Albums are not end-to-end encrypted: they are encrypted in transit and at rest, which means the provider still holds keys that can open your photos. WhatsApp messages are end-to-end encrypted, but photos backed up to iCloud or Google Drive are not unless encrypted backups are turned on.
Yes for new family groups. Every family group created from August 2026 onwards is end-to-end encrypted by default, with nothing to switch on. Groups that existed before then stay encrypted in transit and at rest until an admin enables encryption, at which point the photos and videos already in the library are migrated to encrypted storage. The encryption covers photo and video bytes; EXIF and GPS data are stripped on the device rather than encrypted, so they are never uploaded. Captions, comments, group and album names, and the record that a file exists are not encrypted, and Clann lists this openly in its published protocol specification rather than in the small print.
Each photo or video is encrypted on the sender's device with AES-256-GCM in chunks, using a data key generated fresh for that single file. That file key is wrapped to the family group's key, and the group key is sealed to every member's device with X25519, so keys reach people and never reach Clann's servers. Devices carry Ed25519 identities and sign for each other, so a new phone is admitted because an existing family device approved it, not because the server vouched for it. Group keys are versioned by epoch, so removing a member mints a new epoch they cannot read. Clann's servers store ciphertext and sealed key packages and hold no key that opens them. The implementation and the normative specification, including everything the encryption does not cover, are published at github.com/ClannApp/clann-e2ee.
In Clann, each family group's key is versioned by epoch. When a member is removed, a new epoch is minted and sealed only to the remaining members' devices, so everything uploaded afterwards is cryptographically unreadable to the person who left. They keep access to nothing new, though no app can un-see a photo somebody already viewed or downloaded - which is why Clann also lets admins block downloads and block screenshots for the whole group. In Ente Photos, removing a collaborator revokes their access to that shared album.
For family sharing, in the ways that usually matter, yes. Neither company can see your photos or videos - both encrypt them on your device. Clann goes further on location: EXIF and GPS data are stripped on your phone before encryption and never uploaded, while Ente encrypts that metadata and stores it. Clann can also block screenshots and alert admins to attempts, block downloads per group, and require admin approval before anyone joins, none of which Ente offers. Ente is ahead in two respects: its encryption covers file metadata that Clann leaves unencrypted (captions, comments, group and album names, and upload records), and it has two published third-party security audits.
Neither can see your photos or videos. Clann encrypts them on the sender's device with AES-256-GCM using a separate key per file, with keys held only on family members' devices, and strips EXIF and GPS data before upload. Clann can see captions, comments, group and album names, and the fact that a file exists, who uploaded it and when. Ente encrypts file contents and all metadata, including EXIF creation time, location and description, so it sees essentially only that encrypted files exist. Both companies are blind to the images themselves, which is what matters if your concern is a provider analysing your child's face.
Yes. In an end-to-end encrypted family group, EXIF and GPS data are stripped on your device before the photo is encrypted, so they are never uploaded at all. This is documented in Clann's published protocol specification at github.com/ClannApp/clann-e2ee. It is a meaningful difference from apps that encrypt location data instead of deleting it - encrypted data still exists and can be opened by anyone with a key, while removed data cannot be recovered by anyone.
Read them, then test them. Clann publishes the cryptographic implementation and the normative protocol specification at github.com/ClannApp/clann-e2ee, covering every algorithm, the full key hierarchy, the threat model and a complete list of what the encryption does not cover. The CLN1 file format is pinned by test vectors generated by a second, independently written implementation and reproduced byte for byte by the first - a stronger check on a format than a round-trip test, which only proves a codec agrees with itself. There is also a browser demonstration running that exact format, so you can encrypt and decrypt a file yourself and watch it work. Ente Photos takes a different route to the same goal: its whole stack is AGPL-3.0 and it has published Cure53 audits from 2023 and 2025.
No. Ente's collaboration documentation lists "comment and react" as coming soon, so as of August 2026 shared albums support viewing and contributing photos but not conversation. Clann has comments built in, and group admins can turn commenting off for the whole group if they prefer. For most families this is the difference between an album and a shared family space.
No. Ente's family plan lets up to 6 people share one subscription's storage, but Ente states that each member gets their own private space and members cannot see each other's files unless those files are explicitly shared through an album or link. It is a billing arrangement. Clann's family group is the opposite: one shared timeline that every invited member sees, adds to and comments on by default, with no participant cap.
It depends which half of Ente you use. If you use Ente to share photos with family, that is the job Clann is built for: one shared timeline every member adds to, comments, screenshot blocking, admin approval to join, age tracking, memory books, unlimited storage, and browser access for grandparents that works on encrypted groups too. If you use Ente as the encrypted backup for your entire camera roll, Clann is not a replacement - it is a sharing app, not a phone backup - and Ente's metadata encryption, fully open-source stack and self-hosting are built for a job Clann does not do.
