Terms of use

ERReader. Version of 26 August 2026.

By installing the app you accept these terms, together with Apple's Standard End User License Agreement.

What you get

A non-exclusive right to use the app on devices tied to your Apple ID, for personal, non-commercial reading.

Trial and purchase

• The first three days are unrestricted.
• After that, ten pages a day are free.
• A one-time purchase removes the limit permanently. It is not a subscription: nothing renews and nothing is charged again.
• The purchase is tied to your Apple ID and is restored on your other devices with “Restore purchase”.
• Refunds are handled by Apple under Apple's rules; the developer has no access to payments.

Your books

You add your own books. The app contains no books and provides access to none. You are responsible for the legality of the copies you open.

Translation quality

The substitution is word-by-word and automatic. A Russian noun is inserted in its dictionary form, and the English sentence around it keeps the grammar; verbs and agreement are approximate by design. It exists to teach vocabulary through context, not to convey meaning precisely, and it can be wrong. Do not rely on it where the cost of a mistake is high.

Dictionary

The dictionary is built from Russian Wiktionary data, via the machine-readable extraction at kaikki.org, and is distributed under CC BY-SA 4.0. The frequency lists come from the FrequencyWords project, MIT licence. The derived dictionary is available under the same CC BY-SA 4.0 licence on request to the support address.

Limitation of liability

The app is provided “as is”. To the extent permitted by law, the developer is not liable for indirect damages arising from the use of the app.
