Privacy Policy

Last updated 14 June 2026

In short: Doppio stores your matches and settings on your device. There is no account, no server, no analytics, and no tracking. Doppio does not collect your data.

Doppio is a padel score tracker for iPhone, iPad, and Apple Watch, made by Marco Sanguineti. This policy explains what the app does and does not do with your information.

Information stored on your device

Doppio stores the following on your iPhone, iPad, or Apple Watch so it can keep score and show your history:

The date, time, and length of each match
The scoring format and rules you select
Team or player names, if you choose to enter them
Point-by-point events, the final result, and basic statistics
Your preferences, such as haptics, voice announcements, serve guidance, and side-change prompts

This information stays on your device. It is used only to run scoring, show your match history, generate result cards, and remember your preferences.

No account and no servers

Doppio does not require an account. There is no Doppio server storing your matches, profiles, rankings, or remote sync, and your match history is not uploaded anywhere. If you never share a match, it stays on your devices.

No analytics or tracking

Doppio contains no advertising and no analytics SDKs. It does not request access to your location, contacts, photos, microphone, or camera, and it does not use HealthKit or read any fitness or health data. It does not track you across other apps or websites.

Apple Watch and iPhone sync

When a match is open on your iPhone, Doppio can mirror the score to your paired Apple Watch and send your taps back, so you can score from either device. This happens locally between your paired devices using Apple's Watch Connectivity, and is not sent to any server.

Sharing match cards

If you choose to share a match result, Doppio uses the standard iOS share sheet. The destination you choose, such as Messages, WhatsApp, Mail, or Instagram, then handles that content under its own privacy practices.

TestFlight, the App Store, and crash reports

If you install Doppio through TestFlight or the App Store, Apple may provide crash reports, diagnostics, and any feedback you submit, depending on your settings. This information is used only to fix bugs and improve the app. Apple handles it under its own privacy policy.

Device backups

Your device or iCloud backups may include Doppio's data, depending on your settings. Those backups are operated by Apple, not by Doppio.

Deleting your data

Deleting the app removes Doppio's match history and settings from that device.

Children

Doppio is a general sports app and is not directed at children. It does not knowingly collect personal information from children.

Changes to this policy

If Doppio later adds features such as accounts, iCloud sync, analytics, payments, or HealthKit, this policy and the App Store privacy details will be updated before those features are released.
