WATCHCHECK

Privacy Policy

Last updated: October 18, 2026

WatchCheck helps you evaluate a used watch listing before you buy it. This page explains, plainly, what information the app collects, how it's used, who else sees it, and how you can delete it whenever you want.

Information we collect

Account information. When you sign up, we collect your email address. If you choose Sign in with Apple, Apple gives us an email address, which may be a private relay address that forwards to you. Your password is never seen or stored by WatchCheck in readable form. It's handled by our authentication provider, which stores it in encrypted, hashed form.

Content you provide. When you add a listing, we store what you enter about it (title, description, price, and a source link if you include one) along with any photos you add of the watch. This includes photos you take with your camera inside the app when you choose to.

AI-generated information. When you request an AI insight, valuation or offer evaluation, we generate and store a written assessment and a set of scores based on the details and photos you provided.

Subscription and usage information. If you subscribe to WatchCheck Pro, the purchase is handled by Apple. We receive whether your subscription is active, but not your payment card or Apple ID details. We also keep a count of how many scans your account has used each month so that plan limits apply.

How we use it

We do not use your information for advertising, and we do not sell your information to anyone.

Who we share it with

We use a small number of service providers to run WatchCheck. We don't share your information with anyone beyond what's needed for the app to function:

Supabase, Inc.Hosts our database, handles authentication, and stores uploaded photos.
Anthropic PBCProcesses a listing's photos and details to generate the AI insight, valuation or offer evaluation you request. Anthropic does not receive your email or account information, only the specific listing content needed to answer your request.
RevenueCat, Inc.Helps us manage WatchCheck Pro subscriptions and confirm whether a subscription is active.
Apple Inc.Processes subscription payments and, if you choose it, Sign in with Apple, under Apple's own privacy policy.

We may also disclose information if required to by law, or to protect the rights, safety, or property of WatchCheck or our users.

On your device

Storage and security

Retention and deletion

We keep your information for as long as your account is active. You're in control of it at all times:

Deleting your account is final. We don't retain a backup copy for you to recover later. Deleting your account doesn't cancel a Pro subscription, so cancel it through Apple first so you aren't charged again.

Children's privacy

WatchCheck is not directed at children under 13, and we do not knowingly collect information from anyone under 13. If you believe a child has provided us with personal information, contact us and we'll delete it.

Changes to this policy

If we make material changes to this policy, we'll update the date at the top of this page. Continued use of WatchCheck after a change means you accept the updated policy.
