Version 1.2 · Effective date: October 14, 2026
This Policy describes how the WordToBrain application ("the App", "we") handles data. The data controller is the publisher of the App — an independent developer. This Policy applies to all users of the App.
Unless otherwise stated in Sections 6 and 7, the App does not collect, process, or store personal data as defined by the GDPR (Art. 4(1)) or other applicable law. The App runs locally on your device and does not upload files to our servers.
WordToBrain is a speed-reading app (RSVP) that works mostly offline. The App does not collect, transmit, or sell personal data and makes no network connections to our servers. Your books, reading positions, and settings remain on your device only and are under your control. The mobile versions of the App may display Google AdMob advertising (Section 6); "WordToBrain Pro" subscribers see no ads.
The App's local storage on your device (IndexedDB) may contain: imported books, reading positions, bookmarks, settings, and local session results. This data:
No synchronization. WordToBrain does not sync your library between devices: each device keeps its own library.
Backups. Your device's standard backup and synchronization features (for example, iOS system backups) may include App data stored on the device. Such copying is performed by the operating system at your discretion and is not data processing by the App. We have no access to these backups.
Book import (TXT, FB2, EPUB, PDF, DOC, DOCX) is performed only by you, following your explicit action (file selection or text paste), and is processed locally on your device for reading. Files are not transmitted to us or to third parties.
The mobile versions of the App (iOS and Android) may display interstitial ads through Google AdMob. The web version shows no ads. "WordToBrain Pro" subscribers see no ads.
The "WordToBrain Pro" subscription is purchased and paid for through the store from which the App was installed: the Apple App Store (StoreKit) or Google Play (Play Billing).
We do not sell, rent, or disclose personal data to third parties. Since we do not collect personal data on our side, no transfer of such data — including cross-border transfer — takes place. The exception is data processed by the advertising and payment providers (Sections 6 and 7), under their own policies.
The App does not retain personal data on the publisher's side. The local data described in Section 4 is stored on your device only as long as the App exists and is deleted when you uninstall it or clear its storage.
Local data is protected by the isolation provided by the operating system. Data transfers to the advertising provider (Section 6) use secure connections as required by Google.
The App is not directed at children and does not collect children's data. If you believe otherwise, please contact us via the details below; we store no data that could be subject to deletion.
Since no personal data is collected on our side, a request to exercise rights (access, rectification, erasure, portability) is unnecessary and cannot be fulfilled, as we hold no stored personal data. If you believe protected data nonetheless exists, submit a request via the contacts below; we will respond within the period required by applicable law, confirming that no such data is held. For data processed by the ad provider, contact Google.
Any changes will be announced by publishing an updated version on this page with a new effective date. Material changes may be accompanied by an in-app notice where technically feasible.
