Winston Scientific privacy policy

Winston Scientific is designed as a local-first calculator and study app. It does not require an account, does not include advertising SDKs, and does not use analytics or cross-app tracking.

• No account creation
• No advertising SDK
• No analytics SDK
• No sale of personal data
• No tracking across apps or websites

Calculator history, memory registers, result audits, graphing work, preferences, and settings are stored only on your device using the system preferences store. None of it is transmitted off the device.

The bundled reference data — physical constants (NIST CODATA 2022), unit-conversion ratios (NIST SP 811), and the formula library — is included inside the app, so every feature works fully offline without a developer server connection.

If this policy changes, the updated version will be posted on this page.
