Privacy policy
Elements is a local-only periodic-table study app. It needs no account, sells no personal data, shows no adverts, and uses no analytics or tracking. The data you create stays on your device, in the app's private storage: your study decks and flashcards, your revision history and spaced-repetition schedule, your starred elements, and your settings.
Deletion and reinstall
Deleting a deck removes it. Uninstalling Elements removes study content, history, favorites, and settings from the app sandbox. To prevent repeated use of the introductory access period, small device-only eligibility markers may remain in secure system storage after uninstall and reinstall. They contain access timing and status only—not your identity or study content—and are never sent to the developer.
What we don't collect
We don't collect your name, email, phone number, location, advertising identifiers, contacts, microphone, or usage data. There are no advertising, analytics, attribution, or tracking SDKs.
Purchases
Elements includes 3 days of full access. Starting this access period happens locally on your device and does not create a subscription or charge. After 3 days, a single optional one-time purchase unlocks the whole app permanently—there is no subscription and nothing renews or charges automatically. The App Store (iOS and macOS) or Google Play (Android) handles the purchase; Elements never sees your name, payment card, or billing details. The store is contacted only if you choose to buy or restore the unlock.
Network use
Elements works without sending your data to any server — it has none. The whole periodic table ships inside the app, and normal use stays on your device.
On-device features
Spoken element names use your device's built-in text-to-speech (audio output only — no microphone, nothing recorded). The optional explainer, when available, runs on your device using Apple's on-device model and uploads nothing. Apple Watch sync exchanges your progress directly between your iPhone and Watch, never through a server. The Wear OS app uses bundled element data on the watch and does not sync through any developer server or cloud.
Permissions
Any permission is used only for the feature you choose, such as the optional study reminder or the home-screen widget. You can change these in your device settings.
Children
Elements is rated for everyone, contains no objectionable content, and collects no personal information from anyone — including children.
Changes
If this policy changes, we'll post the updated version here and revise the date above.
