Privacy Policy

Last updated: July 3, 2026

Who we are

AngleMotion (“we”, “us”) is a video-analysis platform for tennis coaches, available at www.anglemotion.com. This policy explains what data we collect, how we use it, and the choices you have. Questions: vinbaccelli@gmail.com.

Your videos stay on your device

Videos you analyze in AngleMotion are processed locally in your browser. We do not upload, store, or view your video files on our servers. When you choose to export, videos go directly from your browser to your own YouTube account, and reports to your own Google Drive.

Information we collect

Account information: when you sign in with Google we receive your name, email address, and profile picture.
Content you create: player profiles, notes, measurements, and analysis screenshots you choose to save are stored in our database (hosted by Supabase) so you can access them across devices.
Payment information: subscriptions are processed by Stripe. We never see or store your card details — we only store your subscription status.
Technical basics: authentication cookies to keep you signed in. We do not run third-party advertising or tracking.

How we use Google user data

AngleMotion requests three Google permissions, used only when you explicitly trigger an export:

Google Docs (create documents): to generate the coaching reports you request.
Google Drive (per-file access): to organize the reports and folders created by AngleMotion in your Drive. We cannot see, read, or modify any other files in your Drive.
YouTube (upload videos): to upload analysis videos you export to your own channel, as Unlisted, on your request.

We never read your Google data for any other purpose, never use it for advertising, and no humans read it. You can revoke AngleMotion’s access at any time at myaccount.google.com/permissions — the app keeps working; only the export features stop.

AngleMotion’s use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

Who we share data with

We do not sell your data. We share it only with the processors that run the service: Supabase (database and authentication), Stripe (payments), Google (only the exports you trigger), and Vercel (hosting).

Data retention and deletion

Your saved content is kept while your account is active. To delete your account and all associated data, email vinbaccelli@gmail.com and we will remove it within 30 days. Reports and videos already exported to your Google Drive and YouTube belong to you and are unaffected by deletion of your AngleMotion account.

Security

Data is transmitted over HTTPS and stored with row-level security so each coach can only access their own data. Google access tokens are used transiently for the exports you request and are not stored on our servers.

Children

AngleMotion is a tool for coaches and is not directed at children under 13. Player profiles created by coaches should comply with local regulations and parental consent where applicable.

Changes to this policy

We will post any changes on this page and update the date above. Material changes will be announced in the app.
