Privacy policy

Effective October 27, 2026

compr is a photo game: someone opens a compr with a few categories, people post a photo for each, everyone votes, and the compr closes at a deadline. This policy explains what compr collects, who can see it, who helps us run compr, how long we keep things, and how to delete them. It covers the compr app on iPhone and Android and the web app at compr.photo. "compr", "we" and "us" mean the team that runs compr.

1. What we collect

Your account

• Email address. You sign in with a code we email you, so your address is how compr knows it's you. We never show it to other people.
• Profile: your name, username, profile photo, a short bio and your home city, if you add them.
• Account records: when you joined and last signed in, and whether your email address has bounced.

What you post and do

• Photos and clips you post, their captions, and whether they came from the camera or your library. On the way up, the app re-encodes photos, which normally drops the location data a camera embeds in the file. Clips are re-encoded on our servers and may keep the recording time and, if your phone saved one, where the clip was recorded.
• Comprs you open: the title, description, categories, deadline and, for public comprs, the place you add.
• Votes, reactions and results: your votes, the emoji reactions you leave, and the points, wins and ratings that come from playing.
• Messages: comments on photos, compr chats and direct messages, including voice messages and GIFs you send.
• Reports you make about photos, comprs, people or messages, including any note you add.
• People: who you follow and who you block.

Technical data

• Push token: if you allow notifications, a token from your phone that lets us send them.
• Sign-in records: for each sign-in, code request and other account event, the time, your IP address and your device or browser type. These help us stop abuse and spot accounts that are under attack.
• Server logs: our servers log each request, with the time, the address requested, your IP address and your account number. We use them to keep compr running and to investigate problems.
• Crash reports: if the app crashes, it may send a crash report with technical details about your device and what the app was doing. It doesn't include your photos or messages.

Guests

If you open a compr link without an account, you can join and vote as a guest. A guest has no email address. We keep the guest's votes and the comprs it joined, linked to that browser or device.

2. Location

compr only asks for your location when you tap "Near me" in Discover or add a place to a compr or your profile, and only while you're using the app. It never tracks you in the background.

• Your phone rounds the position to about 1 km before anything else happens, and turns it into a city name using your phone's own map service (Apple's or Google's).
• Your profile stores only the city, region and country. No coordinates.
• A public compr stores its place name and city, plus the rounded point (about 1 km), so people nearby can find it. Other people see the place name, never the coordinates.
• "Near me" sends the rounded point with the search. It appears in our server logs like any other request.

3. How we use it

• To run compr: sign you in, show your comprs, count votes, work out results and points, and deliver messages.
• To send you email you need (sign-in codes, account notices, results) and the notifications you allow.
• To keep compr safe: screen photos posted to public comprs, review reports, enforce blocks, and stop spam and abuse.
• To fix problems and keep the service working.

We don't sell your personal information, show ads, or share your data for advertising. compr doesn't use analytics or tracking tools.

4. Who can see what

• Public comprs are listed in Discover. Anyone can see them, including their photos, place and results, even without signing in.
• Link comprs can be opened by anyone who has the link.
• Private comprs are for the people in them.
• Link previews: when you share a compr link in a chat app, the preview shows the compr's title and the names and photos of the people in it. Photos from private comprs are blurred in the preview.
• Your profile (name, username, photo, bio, home city and game stats) can be seen by people using compr. Your email address never is.
• Votes: people see vote counts, never who voted for what. Reactions show who reacted.
• Messages: photo comments are visible to whoever can see the photo, compr chats to the people in that compr, and direct messages to the two of you.
• Blocking hides you and the person you block from each other.

Anything you post where others can see it can be saved or screenshotted by them, so share with care.

5. Who helps us run compr

We use a few companies to run compr. They handle your data on our behalf, only to provide their service to us:

• Amazon Web Services (United States): hosts our servers and database, stores and delivers photos, clips and voice messages, and sends our email.
• Anthropic (Claude AI): screens every photo posted to a public compr for content that breaks the rules, and acts as the AI judge when a compr's creator turns that on. For judging, it gets up to six photos per category plus the category's name. A clip is sent as a few still frames. In neither case are names, captions or email addresses sent.
• Expo, Apple and Google: deliver push notifications. A notification can include a compr's title, a person's name, and the start of a message or comment sent to you.
• Giphy: provides GIF search. Searches go through our servers, and GIFs you see load directly from Giphy.
• Sentry: receives crash reports from the app, when crash reporting is on.
• Your phone's map service (Apple or Google) turns a rounded location into a city name, on your device.

We may also share information when the law requires it, to protect people's safety, or as part of a sale or merger of compr, in which case this policy would still apply to it.

6. How long we keep it

• Your account and profile: until you delete your account.
• A photo you remove is erased. If it counted in a compr that has already finished, the result stands and shows a "Photo removed" placeholder. If someone has reported it, we keep it privately until the report is reviewed, then erase it.
• A message you delete disappears for everyone right away. Its content stays in our database, where nobody can see it.
• Photos the safety screen rejects are never shown to others, but we keep them.
• Sign-in records: 90 days, or one year for email changes.
• Server logs: deleted automatically after a few weeks.
• Sign-in codes expire after 10 minutes and are deleted within a week. A signed-in device stays signed in until it has gone unused for 30 days.
• Guests: a guest that never joined a compr is deleted after 30 days. One that joined is kept with its votes.
• Bounced email addresses are kept so we don't keep mailing an address that can't receive it.

When you delete your account

Go to Settings, then Delete account, and confirm with a code we email you. Then:

• You're signed out everywhere, and your email, name, username, profile photo, bio and home city are erased. Your email address and username become free to use again.
• Your follows, followers, blocks and push tokens are deleted.
• Your photos and clips are removed, following the rules for removed photos above. A photo in a compr whose results are still being counted is removed as soon as the results are in.
• Your messages are deleted, as described above.
• Your email address is removed from our sign-in records. Those records otherwise stay until they expire.
• Your votes, reactions, points and the comprs you opened stay, so other people's results don't change, but they no longer carry your name. Other people see "Someone" in your place.

7. Your choices and rights

• Edit your profile any time. Remove your photos, or delete your messages, from the app.
• Delete your account in Settings, then Delete account.
• Turn location and notifications on or off in your phone's settings.
• Block anyone, and report anything that breaks the rules.

Depending on where you live, you may have the right to access, correct, delete or get a copy of your personal data, and to object to or limit how we use it. To make a request, email support@compr.photo from the address on your account. We'll answer within the time the law allows, and won't treat you differently for asking. You can also complain to your local data protection authority.

8. What stays on your device

compr doesn't use cookies. The app and the web app keep your sign-in, a copy of your profile, and settings such as your theme and recent emoji on your device, so you stay signed in. Signing out clears your sign-in from the device.

9. Children

compr is not meant for children under 13, and we don't knowingly collect personal data from them. If you believe a child under 13 is using compr, email support@compr.photo and we'll delete the account.

10. Security

compr is served over encrypted connections. Sign-in codes are stored only in a scrambled form that can't be turned back into the code, and they expire quickly. Deleting an account requires a fresh code from your inbox. No system is perfectly secure, so we can't promise that nothing will ever go wrong. If something does go wrong in a way that affects you, we'll tell you.

11. Changes and contact

If we change this policy, we'll update the date at the top. If the change is significant, we'll also tell you in the app or by email before it takes effect.
