Tenny — Privacy Policy

Last updated: September 4, 2026

Tenny ("the app", "we", "our") is a tennis video-editing app for iOS. It helps you find rallies and swings, review footage with optional tracking overlays, and edit and export clips. This policy describes what data the app handles, where it lives, and what leaves your device.

In one sentence: Tenny processes your practice videos on your device; you choose which videos to import and where to save or share exported clips.

Who runs this app

Tenny is built by Zian Meng as an independent developer.

Data we handle

Stored on your device

Tenny handles the following on your device:

• Videos you choose to record or import through Photos or Files. Camera and microphone permissions support in-app recording when you choose it.
• Detected rallies and swings, your editing selections, and body-pose, racket, or ball overlay data generated during review
• Your session library, per-session notes, and app settings

Tenny can keep its own video copies or reference a file at the location you selected through Files. Tenny-owned source clips are excluded from device backups; this does not change the backup or sync settings of your original Photos or Files items.

Rally and swing detection and the available body-pose, racket, and ball overlays run on your device using local analysis and bundled models. Tenny's video-editing experience does not upload your practice videos to a cloud-coaching provider or display coaching grades and drill recommendations.

Media selection and export

You choose videos through the system Photos or Files picker. Exporting creates a clip you can save or share using the destination you choose. Files you save outside Tenny are controlled by that destination and your own storage and sharing settings.

Subscriptions

Tenny Pro is sold through Apple's In-App Purchase system. Apple processes the payment; we never see your payment details. The app uses StoreKit purchase and subscription status to determine access to Tenny Pro.

Not collected at all

Tenny does not:

• Require or create user accounts — there is no sign-up in this version
• Operate a developer-run server that receives your data
• Use analytics SDKs (no Firebase, Mixpanel, Amplitude, etc.)
• Include advertising SDKs or trackers of any kind
• Sell, rent, or share your data with anyone
• Collect location, contacts, browsing history, or device identifiers

Your rights and controls

You can at any time:

• Delete a session — remove its library entry and analysis. Tenny removes its own source-video copy when no remaining session uses it; your original external files are not deleted.
• Remove local app data — uninstall the app. Original media and exported clips saved outside Tenny remain in their chosen locations.
• Control media access — choose which videos to import and manage camera and microphone permissions in iOS Settings
• Export your clips — save analyzed clips to your photo library or share them wherever you choose
• Ask for help — email workingzian@gmail.com

For EU/UK residents (GDPR)

You have the right to access, correct, delete, or port your data, and to object to processing. Because Tenny does not operate a server, your data lives on a device you control — these rights are exercised directly through the app and your device. For anything you cannot resolve that way, email the contact address above.

For California residents (CCPA)

We do not sell your personal information. The categories described above are all we handle.

Children

Tenny is a general-audience sports app. It is not directed at children under 13, and we do not knowingly collect personal information from children under 13. A parent or guardian with a concern about a child's data can contact us.

Security

• Local data is stored in the app's sandbox, protected by iOS's file encryption
• Practice-video analysis takes place on your device
• No developer-run server means no server-side database of your content to breach

No system is perfectly secure. If you discover a security issue, please email workingzian@gmail.com before disclosing it publicly.

Changes to this policy

If this policy changes, we will update the "Last updated" date at the top. Material changes will be surfaced in the app as well.
