### 3/5 — Проблема с приватностью

*2026-03-13*

Уважаемый разработчик!

При всём уважении к проделанной работе, хочу поделиться важным замечанием по механике приложения AirLock (версия 1.2, iOS 26.3.1).

1.  Было бы намного удобнее, если бы приложение имело полноценную клавиатуру-расширение (как в PGP Everywhere), а не только отдельное окно для вставки текста. Набирать и шифровать прямо во время ввода — это значительно удобнее.
2.  Главная проблема безопасности: расшифрованный текст сразу появляется в диалоговом окне мессенджера. Это позволяет приложению-хосту прочитать и залогировать открытый текст до отправки. Таким образом, вся польза от шифрования сводится к нулю в сценариях, где мессенджер может мониториться.

Чтобы приложение действительно решало задачу приватной переписки, очень прошу рассмотреть два улучшения:

-   Встроить клавиатуру, где набираемый текст отображается ТОЛЬКО внутри самой клавиатуры (не попадая в поле чата).
-   При расшифровке показывать открытый текст тоже только внутри окна клавиатуры (с возможностью копирования вручную).

В App Store почти нет альтернатив с такой механикой, поэтому реализация этих функций сделает AirLock по-настоящему уникальным и безопасным инструментом. Буду очень благодарен, если учтёте замечания в следующем обновлении. Готов протестировать!

Спасибо за приложение!

### 3/5 — Requires full access

*2025-09-24*

I absolutely love the idea of this app. Unfortunately, I won’t use it because it requires full access but there appears to be no proof of its privacy and security claims. Keyboards are incredibly important to keep secure because people type secrets with them, and a keyboard with full access is capable of logging and extricating everything typed. To grant a keyboard full access should require proof that each version of keyboard does not log typing. The AppStore review isn’t enough of a guarantee. Please consider how you can provide this proof. You’ve created a great product with great power, but using it shouldn’t require trust.

**Developer response:** Thanks a lot for the feedback, but you can still use the app even without providing full access, regarding proofs I will think about how to provide it 👌😊
