Privacy Policy

Last updated: July 2026

StackXo ("we", "our") is a session tracking app for poker players. This policy explains what data we collect and how we use it.

Data we collect

• Account info: email address and display name, provided when you sign up with email, Apple, or Google.
• Session data you enter: poker session records (dates, buy-ins, results, locations, game types, notes).
• Feedback messages: messages you send us through the in-app feedback channel, along with your device platform and app version.
• Photos you scan: when you scan a tournament clock or blind structure, the photo is sent to our server and on to Google's Gemini API, which reads the text in the image and returns it. We do not store the photo — only a record that a scan happened, so we can count it against your monthly allowance.
• Location (optional): if you grant location access, the app may use your device location while you are using it to suggest the room you are playing at. You can decline, and you can change this at any time in your device settings.

Analytics

We use PostHog (PostHog, Inc., United States) to understand how the app is used — which screens people open, and whether features such as importing sessions actually work. PostHog processes this data on our behalf.

• What we send: the screens you open, a small set of named product events (for example, that a session was started or saved), your app version, device type and operating system, and an account identifier (a random ID assigned by our database).
• What we never send: your email address, your session notes, and any monetary amounts. Buy-ins, results, and bankroll figures never leave the app for analytics.
• Session replay: we may record replays of app sessions to diagnose problems and improve the app.
• Diagnostics: we may collect crash reports and performance data to fix problems.
• We do not use advertising identifiers (such as Apple's IDFA), and we do not track you across other apps or websites.
• Analytics data is stored in the United States and retained for up to 12 months.

To opt out of analytics, contact us at support@stackxo.app.

How we use it

• To provide the app: store and sync your session data across devices.
• To authenticate you and secure your account.
• We do not sell your data or share it with third parties for advertising.

Where it's stored

Your data is stored with Supabase (our backend provider) on secure cloud infrastructure. Authentication is handled by Supabase Auth with Apple and Google sign-in options.

Service providers we use: Supabase (database, authentication), PostHog (analytics), RevenueCat (subscription management), and Google Gemini (reading text from photos you scan). They process data on our behalf and are not permitted to use it for their own purposes.

Your rights

• You can delete your account and all associated data at any time from within the app (Settings → Delete Account). See how to delete your account.
• You can request a copy or deletion of your data by contacting us.
