Who we are

You Know Who is made by Scherer Luck LLC ("we", "us"). It helps you look up a phone number before you call it back or answer it, using public web results and reports from other people who use the app.

What we collect

• Account: your name, your email address and your password. Your password is stored in scrambled form by our sign-in service; we never see it.
• Numbers you check: the phone numbers you type into Search or Scam Check, the result, and the time. They are saved to your history so you can open them again.
• Your lists: My Block List and your settings are kept on your phone. If you use Cloud Backup, a copy is kept in your account, together with the model name of your phone.
• Reports and votes you send to the Community Spam Database.
• Subscription details: whether you have a trial or a plan, which plan, and the renewal dates. Your card details go straight to Stripe, our payment provider. We never see or store your card number.
• Usage counts: each time you check a new number we record the time, but not the number, so we can apply the daily limit.

What we do not collect

The app does not read your contacts, call history, text messages, microphone, camera or location, and it does not see your incoming calls. It contains no advertising and no third-party analytics tools.

How we use it

To run the checks you ask for, keep your history, restore your backup, apply the daily limit, manage your subscription, keep the community database useful, and prevent abuse of the service. We do not sell your personal information.

Companies that help us

• Supabase hosts our database and sign-in.
• Brave Search: when you check a number, the number is sent to Brave Search as a search, to find public web pages that mention it.
• Anthropic (the Claude AI): Scam Check uses an AI model to write the plain-English explanation. It is given our rating, a count of reports and short excerpts from public web pages. The phone number you checked is replaced before anything is sent, and your name and email are never sent.
• Stripe handles payments and subscriptions. It receives your email address and the payment details you enter on its secure page.

Community Spam Database

When you report a number, the number, the category, your description and the area the number belongs to are added to a database that all users of the app can see. It is not shown with your name. If you delete your account, the link between you and your reports is removed, but the reports themselves stay because they are about the phone number.

Keeping and deleting your data

We keep your information while your account is open. To delete it, go to Settings > Delete My Account. That permanently deletes your account, your history and your cloud backups, and it cancels any Premium subscription and removes you from Stripe so you are never charged again. Stripe may keep payment records that the law requires it to keep.

Security

Information travels over encrypted connections, and the database is set up so that each person can only read their own history, backups and subscription. No system is perfectly secure, so we cannot promise absolute security.

Children

The app is not meant for children under 13, and we do not knowingly collect information from them.

Your choices

You can see your history in the app, remove items from it, and delete your whole account in Settings. Depending on where you live you may have further rights, such as asking for a copy of your information. Ask us and we will help.

Changes

If we change this policy we will update the date below, and for important changes we will tell you in the app.
