Effective as of 2026-07-03
This policy describes what data the Yomi (読み) iOS application handles and where it goes. The short version: your books live on your device, there are no accounts, no ads, and no analytics — and text leaves your device only when you ask for a paid AI feature.
Books you import (EPUB, PDF, TXT) are stored locally on your device. Reading them — including furigana and dictionary lookups, which are computed on-device — sends nothing anywhere. Deleting a book removes it and its generated audio from your device.
Two features send parts of your content off the device, and only when you explicitly request them:
This content is processed to produce the result and returned to your device, where it is stored (generated audio is cached locally and can be cleared in Settings). We do not build a library of your content on our servers. The third-party providers process the data under their own terms: ElevenLabs, Google, Cloudflare.
Subscriptions are processed by Apple and managed through RevenueCat, which assigns an anonymous identifier to your installation and stores your purchase and entitlement state. That anonymous identifier accompanies paid requests to our proxy server so it can verify an active subscription; the verification result is cached server-side. We never see your payment details — Apple handles billing.
The app is not directed at children under 13, and we do not knowingly collect personal information from children.
All network communication uses HTTPS. Paid requests are authorized against your anonymous subscription identifier server-side; API keys for AI providers never leave our servers.
We may update this policy from time to time. The current version is always available at this page; the effective date above reflects the latest revision.
By using the app, you consent to this policy. Questions or requests: jisho_ai@proton.me
