Privacy policy

Effective 10 November 2026

Who we are

Optic is made by AceCode, Warsaw, Poland ("we", "us"). If you have a question about this policy, write to support@optictennis.com.

What Optic uses on your iPhone, and why

Optic asks for each permission when it first needs it. You can change your answer any time in the iPhone Settings app.

• Camera: to record your serves.
• Microphone: the sound of the ball on the strings helps Optic tell a real serve from a practice swing. The sound is saved with the clip.
• Motion: to notice when the phone has been moved, so measurements stay comparable.
• Photos: to open the videos you choose to import. With access, Optic loads the original of the video you picked; without it, Optic uses the copy the photo picker hands over. Optic doesn't look through your library and doesn't save anything to it.
• Files: to open the videos you choose to import from the Files app.

What Optic stores

Everything stays in Optic's own storage on your iPhone:

• the videos you record or import, and the sessions made from them;
• the measurements Optic takes from those videos, such as body positions and joint angles, the path of the ball, timing, scores and, when racket tracking runs, the position of the racket;
• the player profiles you create: a name, which hand the player serves with and, if you add it, a height;
• your settings.

Optic's files are visible in the Files app (On My iPhone › Optic). If you have iPhone or iCloud backups turned on, they're included in your backups, which Apple handles under its own privacy policy.

All of the analysis runs on your iPhone: body, ball and racket tracking, scoring, the coach's note (written by Apple's on-device language model, Apple Intelligence) and spoken results (the iPhone's built-in voice). None of it sends your data to us or to anyone else.

What we receive

Nothing from the app itself. Optic has no account, no servers, no ads, no analytics and no tracking, and it doesn't share data with third parties. There are two exceptions, and both are your choice:

• Support email. If you write to us, we receive your email address and whatever you send, such as a clip or session file you attach. We use it only to answer you and fix the problem, and we delete it when you ask us to.
• Crash reports from Apple. If you've chosen to share analytics with app developers in your iPhone settings, Apple sends us crash reports and basic usage statistics. They don't identify you to us.

Sharing from the app

When you share a clip or a session file, it goes where you send it, such as Messages, Mail, AirDrop or another app. From there, that service's privacy policy applies.

Deleting your data

• Delete a single session in the app.
• Settings › Delete all sessions removes every recording and measurement.
• Deleting the app removes everything Optic stored on the phone. Copies in your backups follow your backup settings.
• To have us delete a support conversation, email support@optictennis.com.

Children

Optic doesn't collect personal data from anyone, including children. If a junior player uses Optic, their videos and profile stay on the phone it's used on, like everyone else's.

Your rights

Depending on where you live (for example in the EU or the UK under the GDPR, or in California), you have the right to access, correct or delete personal data we hold about you, and to complain to your data protection authority. Because the app sends us nothing, the only personal data we could hold is support email. Write to support@optictennis.com and we'll respond within 30 days.

optictennis.com uses no cookies, no analytics and no tracking, and it serves its own fonts. It's hosted by Vercel, which processes visitors' IP addresses to deliver the site and keep it secure; see Vercel's privacy policy.

Changes

If this policy changes, we'll update this page and the date at the top. If Optic ever starts sending data off your phone, we'll say so here and in the app before it happens.
