StudyForge Privacy Policy

Effective date: November 12, 2026

This policy explains what StudyForge: AI Flashcards ("StudyForge", "the app") collects, why, and who it is shared with. StudyForge is made by BeaconAI LLC ("BeaconAI", "we", "us"). It covers the Android and iOS apps.

The short version:

• Your PDFs never leave your phone. Only the text of the section you ask about is sent for AI processing, and we keep none of it.
• You don't create an account. The app identifies itself with a random ID that isn't tied to your name, email or phone number.
• The free version shows ads from Google AdMob. Where the law requires it, we ask your consent before ads use your data.
• Purchases go through Google Play or the App Store. We never see your payment details.
• We do not sell your personal information.

What stays on your phone

Most of what StudyForge handles never leaves your device. It is stored in the app's private storage, which other apps can't read.

• Your PDFs. The app reads the file you pick and extracts its text on your phone. The PDF itself is never uploaded.
• Extracted text and sections. The text and the sections it is split into are stored on your phone.
• Your study content. Summaries, flashcards, quizzes, review history and quiz scores.
• Forge Points, streaks and badges. Your points balance, its history, streak freezes and badges.
• Settings. Theme, onboarding status and your last known subscription tier.
• Your install ID. A random identifier created the first time you open the app. It isn't linked to your name, email, phone number or Google or Apple account.

If your phone's own backup is turned on (Google backup on Android, iCloud on iOS), this data may be included in that backup. It goes to your own Google or Apple account, not to us.

What leaves your phone, and why

StudyForge sends data off your phone only for the five purposes below.

1. Generating study content. When you ask for a summary, flashcards or a quiz, the app sends that section's title and text, and how many pages it covers, to StudyForge's server. The server forwards it to Anthropic, whose Claude AI model writes the content, then returns the result to your phone. Our server doesn't store the text and doesn't log it.
2. Counting your weekly AI pages. Each request carries your install ID. Our server keeps the install ID with a count of pages used this week, any bonus pages you redeemed with Forge Points, and a count of today's requests. These counters expire on their own: the weekly page and bonus counts 8 days after they were last updated, and today's request count after 2 days. They are how we enforce the free and paid limits without accounts.
3. Checking the app is genuine. Each request includes a token from Google's Play Integrity (Android) or Apple's App Attest (iOS), issued through Firebase App Check. It proves the request came from a real copy of StudyForge. Our server checks the token and records only whether it was valid.
4. Showing ads (free version only). Google AdMob receives device and usage information to choose and measure ads. See "Ads and your choices" below.
5. Subscriptions. If you subscribe, Google Play or the App Store handles the payment. RevenueCat receives the purchase record and your install ID so the app knows you're subscribed. We never receive your card or bank details.

We don't use analytics or tracking tools beyond these, and we don't build profiles of you.

Services we use

These companies process data for StudyForge. Each one handles it under its own privacy policy.

Anthropic does not use this text to train its models by default, and deletes it from its systems within 30 days. It may keep data longer only where needed to enforce its usage policy or to comply with the law. Source.

Ads and your choices

The free version of StudyForge shows banner ads from Google AdMob. Ad-Free and Pro subscribers see no ads, and no ad requests are made for them.

• What AdMob uses: your device's advertising ID, IP address, device type and settings, and how you interact with ads. Google uses this to choose ads, limit how often you see them, measure them and prevent fraud.
• Consent in the EEA, UK and Switzerland: before any ad loads, the app shows Google's consent form. You can accept or decline personalized ads. If you decline, you may still see ads that aren't personalized. You can change your choice any time under Settings → Privacy choices.
• Your advertising ID: you can reset or delete it in your phone's settings (Android: Settings → Google → Ads; iOS: Settings → Privacy & Security → Tracking).
• On iOS: StudyForge does not ask to track you across other companies' apps and websites, so ads on iPhone aren't personalized with that tracking.
• Google's policies: How Google uses information from sites or apps that use its services.

How long we keep data, and deleting it

To delete your data:

• In the app: Settings → Delete all my data erases your documents, study content, points and badges from the phone. Your install ID stays, so your weekly AI limit and subscription stay attached to this copy of the app.
• Everything: uninstall StudyForge. That removes all app data, including the install ID. The counters on our server then expire on their own.
• Subscription records: email us (see Contact) with your install ID from Settings → About, and we'll ask RevenueCat to delete its record. Cancel the subscription itself in Google Play or the App Store.

Your rights

Depending on where you live (for example under the GDPR in the EEA and UK, or state laws such as California's CCPA), you may have the right to access, correct, delete or move your personal data, to object to or limit how it's used, and to withdraw consent. Because we hold almost nothing that identifies you, most requests are handled by the delete options above. For anything else, email us with your install ID. We'll answer within 30 days. You can also complain to your local data protection authority.

Legal basis (EEA and UK): we process your section text and install ID to provide the service you asked for. We run integrity checks and request limits for our legitimate interest in preventing abuse. Personalized ads rely on your consent.

We don't sell or share your personal information for cross-context behavioral advertising as those terms are defined in California law, other than through ads in the free version, which you can limit as described above.

Children

StudyForge is not directed at children under 13, and we don't knowingly collect personal data from them. If you believe a child under 13 has used the app, contact us and we'll help remove what we can.

Security

Data sent from the app travels over encrypted HTTPS connections. API keys stay on our server and are never in the app. Requests are checked for a genuine copy of the app and limited per install. No system is perfectly secure, but we keep what we hold to a minimum.

Changes to this policy

If we change this policy, we'll update the effective date above. For significant changes we'll also tell you in the app before they take effect.
