Grooved · Privacy Policy

Your video never leaves your phone.

Grooved analyses your tennis swing on your iPhone. This policy describes what happens to your data, and the short version is that almost nothing happens to it, because it never leaves your device.

Last updated: 22 July 2026

The short version
1
Your videos are never uploaded. Analysis runs entirely on your iPhone.
2
There is no account. We do not know who you are.
3
We collect no analytics, run no advertising, and use no third-party trackers.
4
Deleting the app deletes everything.
What Grooved stores, and where

Everything below is stored only in Grooved's private container on your device. None of it is transmitted anywhere.

WhatWhyWhere
Videos you record or importTo analyse and replay your swingsOn your device
Extracted pose data and keyframesTo draw the skeleton and compute metricsOn your device
Consistency scores and metric historyTo show your trend over timeOn your device
Practice progressTo track which sessions you have completedOn your device
Settings such as handedness and languageTo configure the appOn your device

Videos you import from your photo library are copied into Grooved's own storage so analysis can run. That copy is deleted when you delete the session.

What Grooved does not do
Camera, photo library, and microphone

Grooved asks for these only when you use the feature that needs them.

You can revoke any of these in Settings, then Grooved. The rest of the app keeps working.

Sharing a clip

When you tap share, Grooved hands the file to the iOS share sheet and you choose where it goes. Grooved does not transmit it anywhere itself, and it has no record of what you shared or with whom. Once a clip is in another app, that app's own privacy policy applies.

Purchases

Subscriptions and purchases are processed by Apple, not by us. We never see your payment details. Apple tells the app whether an entitlement is active, and nothing more. Apple's handling of that transaction is governed by Apple's Privacy Policy.

Your data rights

Because your data is on your device and we hold no copy, you exercise every right directly:

We cannot access, restore, or delete your data on your behalf. We do not have it. This also means there is no backup: if you delete the app, your history is gone. iCloud device backup may include it depending on your iOS settings, which is between you and Apple.

Children

Grooved is rated 4+ and is safe for all ages. We do not knowingly collect personal information from anyone, including children, because we do not collect personal information at all.

Changes to this policy

If Grooved ever adds a feature that transmits data, this policy will be updated before that feature ships, and the change will be described in the app's release notes rather than made quietly.
