Periodic Table: Elements — Privacy Policy

What Elements does not do

• No accounts. Elements never asks for a username, email, phone number, or login of any kind. There is no server-side account, because there is no server.
• No analytics. Elements includes no Firebase, Google Analytics, Mixpanel, Amplitude, Sentry, Crashlytics, or any other analytics or telemetry SDK. There are no tracking pixels, no install pings, no usage counters.
• No advertising. Elements shows no ads and links to no ad networks.
• No network from Elements. The app has no server of its own and makes no network requests of its own — no endpoint to call, no sync service, no remote logging. The entire periodic table, every element page, the artwork, and the spectra ship inside the app. Your study data never leaves your device. The one exception is the optional in-app purchase, which Apple’s App Store or Google Play handle on their own servers (see Purchases).
• No cloud service. Elements does not use iCloud sync, Google Drive, or any third-party cloud. Your decks and study history live in the app’s private sandbox on your device. (If you back up your device to iCloud or Google, your Elements data is included in your own private device backup; the developer has no access to it.)
• No third-party sharing. Elements does not share, sell, or rent your data to anyone, because Elements has no data to share. There is no cross-app or cross-site tracking.

What Elements stores on your device

The following lives in Elements’s sandboxed app storage and is visible only to Elements on your device:

1. Your study material — the decks and flashcards you study or build, including any custom drills.
2. Study history — your review records and each card’s spaced-repetition schedule (the data needed to decide when to show a card next), plus your study streak.
3. Starred elements — the elements you mark as favorites.
4. Settings — your preferences, such as the appearance (dark/light) and the optional study-reminder time, plus a flag that records you have seen the welcome screens.
5. Access eligibility markers — small device-only records in secure system storage that prevent repeated use of the introductory access period. They contain access timing and status, not your identity or study content, and are never sent to the developer.

The home-screen widget renders from the app’s own bundled element data on your device; it needs no shared account and makes no network request. Deleting a deck removes it. Uninstalling Elements removes study content, history, favorites, and settings from the app sandbox. The device-only access eligibility markers described above may remain in secure system storage after uninstall and reinstall.

Spoken element names

Elements can read an element’s name aloud using your device’s built-in text-to-speech. This is audio output only — Elements does not use the microphone, does not listen, and records nothing. No audio is saved or sent anywhere.

Notifications

If you turn on the optional study reminder, Elements schedules a local notification on your device at the time you choose. It is scheduled and delivered entirely on-device — no notification content leaves your device, and Elements sends no push notifications from any server.

Watch apps

If you use the Apple Watch app, your study progress is exchanged directly between your iPhone and your paired Watch using Apple’s on-device device-to-device connection. This sync does not pass through any server or cloud belonging to the developer. The Wear OS app uses bundled element data on the watch and does not use a developer server or cloud sync.

On-device explainer (Apple Foundation Models)

On a supported device with Apple Intelligence enabled (iOS 26+ or macOS 26+), Elements may use Apple’s Foundation Models framework to phrase a short plain-language explanation of an element. This processing happens entirely on your device: your request is not uploaded, and the result is not stored or sent. If Apple Intelligence is not available, Elements simply uses its bundled written content instead — no network is involved either way.

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.

Children

Elements does not knowingly collect any data from anyone of any age, because it collects nothing. The app contains no objectionable content and is rated 4+ (and the equivalent “everyone” rating on Google Play).

Your rights

Because Elements collects no data and keeps everything on your device, exercising rights under the GDPR, CCPA/CPRA, LGPD, or similar laws is straightforward: open the app to access your study data; delete a deck to remove it; or uninstall the app to remove study content, history, favorites, and settings from the app sandbox. Device-only access eligibility markers may remain in secure system storage as described above. There is nothing to opt out of, because nothing is sold, shared, or transmitted.

Changes to this policy

If Elements ever changes a privacy-affecting behaviour, this document will be updated and the change summarised here with the effective date. Elements’s current design does not permit collecting, transmitting, or sharing your data; adding any such behaviour would require new code.
