Privacy Policy
Last Updated: 2026
NumberLab was built to run entirely on your device. This policy explains, plainly, what that means for your data.
Information Collection
NumberLab does not collect any personal information. There is no account or sign-up of any kind, and nothing you type or bookmark is transmitted anywhere. Numbers you analyze and entries you save stay in local storage on your device only.
Permissions
NumberLab requests zero device permissions. It does not access your camera, storage, contacts, location, or any other device feature, because none of its features require them.
Third-Party Services
NumberLab does not integrate any third-party software development kits, analytics tools, or tracking libraries. No data is shared with any outside company because no data ever leaves your device.
Advertising
NumberLab displays no advertisements of any kind and contains no ad networks.
Offline Functionality
Every feature in NumberLab — every calculation, conversion, and saved entry — works fully offline. An internet connection is never required to use the app.
Children's Privacy
NumberLab does not knowingly collect information from anyone, including children, because it does not collect information from anyone at all.
Changes to This Privacy Policy
If this policy is ever updated, the revised version will appear here with a new Last Updated date reflecting the change.
