Privacy Policy
Last updated: September 27, 2026
Compatable helps you check restaurant menus and packaged foods against your dietary needs and allergies. We collect as little as we can. This page says exactly what leaves your phone, why, who handles it, and how to remove it.
You don't need an account
Everything Compatable does, it does without an account. An account is optional and exists for one reason: to keep a backup of your profile and saved menus so you can pick them up on another phone.
What stays on your phone
- Your profile: dietary needs, allergies, severity settings, excluded foods, goals and favourite foods. Without an account it never leaves your phone except as described under "What is sent when you scan".
- Menu and label photos. They are read on your phone with Apple's on-device text recognition. The photo is not uploaded.
- Photos attached to saved menus. They stay on your phone, even if you have an account.
What is sent when you scan
- Menu and label text. The text read from your photo goes to our servers so an AI model can identify the dishes and ingredients. It describes the food, not you.
- Your dietary needs, with a scan or a "find places near me" request, so the answer fits you. They are used to answer that request.
- Package-front photos. When you photograph a package without its ingredient list in the frame, that photo is uploaded, because identifying the product cannot be done on the phone. It is sent to our server and to our AI provider to be analyzed, and it is not kept after the answer is returned. The product's name is then looked up on the web (manufacturer and retailer pages) to read its ingredient statement.
- Approximate location, only when you ask for places near you. It is used for that request and not kept as a history.
- A random install identifier, so one phone cannot use more than its share of the service. It is not linked to your name or email.
If you create an account
We store, on our servers, tied to your account:
- Your email address, or, with Sign in with Apple, the address Apple gives us (which can be Apple's private relay address, so we never learn your real one), and the identifier Apple or Google assigns to your account with us.
- Your profile: the dietary needs, allergies, severities, excluded foods, goals and favourite foods listed above.
- Your saved menus, as text, without their photos.
We use them only to back up and restore your profile and saved menus, and to keep the service secure. We treat dietary and allergy information as sensitive health-related information. It is never used for advertising or marketing, never sold, and never shared except with the service providers below, who handle it only to run Compatable.
There are no passwords. You sign in with Apple, with Google, or with a one-time code we email you.
Who handles your information
- Supabase hosts our database, accounts and servers. Data is encrypted in transit and at rest. Each account's data can be read and changed only by that account.
- Anthropic (Claude) analyzes menu text, label text and package-front photos. We send the food content and your dietary needs. We do not send your name, email or account identifier.
- Google Places provides restaurant names, locations and photos for the nearby features.
- Apple and Google, if you sign in with them. They tell us your email address and an identifier; we do not receive your password.
- Resend delivers sign-in codes to your email address.
What we don't do
No advertising. No trackers. No analytics SDKs. We never sell data. Crash reports are anonymous and contain no profile content.
Keeping it and deleting it
- Delete your account in the app: Profile, your account, Delete account. Your account, your backed-up profile and your saved menus are removed from our servers immediately. Encrypted backups that include them expire within 7 days. If you signed in with Apple, we also revoke Compatable's access with Apple.
- The profile on your phone stays until you remove it or delete the app.
- If you never make an account, there is nothing on our servers to delete beyond the scan requests described above, which are not kept as a profile of you.
- Restaurant menus and dish information we have analyzed may be cached so the next scan is faster. That describes restaurants, not people.
Your choices
You can use Compatable without an account, sign out, sign out of all devices, or delete your account at any time in the app. For a copy of what your account holds, or any question, email hello@compatable.app.
Children
Compatable is not directed at children under 13, and accounts are for people 13 and older. Adults may add family members' dietary needs to their own profile.
Changes
When this policy changes we update this page and the date above. If a change affects what an account stores, we tell you in the app first.
