Privacy Policy · Last updated June 4, 2026
PeriodicTable is built with privacy as the foundation. We collect no personal data, make no network requests, and store everything locally on your device.
None. PeriodicTable does not collect, store, or transmit any personal data to external servers.
The only data stored is your element bookmarks and decomposition search history, stored exclusively on your device. This data never leaves your device.
PeriodicTable contains a built-in database of all 118 chemical elements with their properties. The item decomposition feature uses pre-computed data to break everyday objects into their elemental composition. All processing happens entirely on your device.
PeriodicTable contains no analytics SDKs, no advertising frameworks, no crash-reporting services, and no tracking libraries of any kind.
PeriodicTable does not request any special system permissions. The app works entirely offline with no access to Contacts, Camera, Microphone, Location, or any other sensitive system resource.
PeriodicTable does not collect any data from any user, including users under the age of 13. The app is safe for all ages and is designed as an educational tool.
If we ever update this policy, the revised version will be posted at this URL. For a purely offline, no-data app like PeriodicTable, we do not anticipate significant changes.
