TackSense Privacy Policy

Effective date: 5 May 2026

TackSense is designed as a simple sailing utility. The app helps users estimate point of sail, sail setup, trim guidance, and conservative sailing warnings based on wind direction, boat heading, wind speed, and gust speed entered or selected by the user.

Data Collection

TackSense does not collect personal data.

The app does not require an account, does not ask for your name, email address, phone number, contacts, photos, or precise location, and does not transmit your sailing inputs to a server.

On-Device Processing

Wind direction, boat heading, wind speed, gust speed, and related sailing calculations are processed locally on your device. These values are used only to display sailing guidance inside the app.

Location, Compass, and Motion Data

If TackSense uses device sensors such as compass, heading, motion, or location in a future version, that data will be used only to provide app functionality and will remain on the device unless this policy is updated. The current privacy intent is: no server upload, no tracking, and no sale of data.

Analytics and Tracking

TackSense does not use third-party advertising, third-party tracking, cross-app tracking, or data brokers.

TackSense does not sell user data.

TackSense does not use analytics SDKs unless clearly stated in a future version of this policy.

Apple App Store Privacy

Apple may collect certain diagnostics, crash, purchase, or usage information through App Store, TestFlight, or device-level services according to Apple’s own privacy practices. The developer of TackSense does not receive personal sailing input data from the app.

Children’s Privacy

TackSense is not designed to collect information from children. Since the app does not collect personal data, it does not knowingly collect personal information from children.

Safety Notice

TackSense provides general sailing guidance based on limited inputs. It is not a substitute for seamanship, weather judgment, navigation, local regulations, proper training, or the skipper’s responsibility. Conditions at sea can change quickly. Use conservative judgment.

Changes to This Policy

This privacy policy may be updated if TackSense adds features that affect privacy, such as optional analytics, cloud sync, accounts, location-based functions, or Apple Watch synchronization. Any material change should be reflected in this policy before release.
