Zenlygram Privacy Policy

Last updated: September 25, 2026

Summary

Zenlygram's developer does not sell any of your data, and receives no analytics, telemetry, or crash reports from the app. Messaging itself never touches the developer: it goes straight between your device and Telegram. The developer operates exactly one server, and only for the Zenlygram Pro subscription — it is described under Zenlygram Pro subscription below, together with what it receives. Some features connect your device directly to third-party services; they are listed below too.

Telegram network

Zenlygram is an unofficial client for the Telegram network. All messaging traffic goes directly between your device and Telegram's servers using Telegram's official API (MTProto). Your messages, contacts, and account data are governed by the Telegram Privacy Policy. Zenlygram is not affiliated with Telegram FZ-LLC.

Data stored on your device

Chat history caches, settings, PIN hashes for Chat Lock and Secret Vault, and other app data are stored only on your device (and in your device Keychain). Call recordings are stored on your device too, and can be uploaded to your own Telegram Saved Messages if you ask for that — see Call recording.

Two optional features keep extra copies of messages. These copies are kept only in the app's local database on this device and are never uploaded:

• Show Deleted Messages is on by default, and you can turn it off in Zenlygram settings at any time. While it is on, messages removed by others are kept on this device instead of disappearing. Telegram doesn't say who deleted a message, so in private chats and small groups, messages you delete only for yourself on another device may also be kept. Kept messages are removed automatically after 30 days, and at most 5,000 are kept per account.
• Edit History is on by default and has its own switch in Zenlygram settings. While it is on, the app keeps up to 20 earlier versions of each edited message, and versions older than 30 days are removed automatically.

Turning either feature off deletes the copies it kept on this device and stops it from keeping new ones.

If you had already chosen to turn either feature off in an earlier version of Zenlygram, that choice is kept; the new default applies only where you had not chosen.

Call recording

If Zenlygram offers call recording in the build you are running, it records only calls you start recording yourself, after a one-time consent screen, and it records both sides of the conversation — your voice and the other person's. Recordings are written to this app's own storage on your device, are excluded from iCloud and Finder backups, and are not synced. The developer never receives them.

A recording can leave your device in two ways, and only if you choose one of them:

• Sharing a recording through the iOS share sheet, which hands it to whichever app or person you pick.
• Sending it to your own Telegram Saved Messages, either by choosing that for one recording or by turning on Send to Saved Messages in Zenlygram settings, which is off by default. Saved Messages is a Telegram cloud chat: a recording sent there is uploaded to Telegram's servers, is stored there under the Telegram Privacy Policy, and is not end-to-end encrypted. The copy on your device is deleted only after Telegram confirms the message was sent; until then the recording stays on the device and nothing is lost if you are offline.

While the setting is off, no recording is uploaded on its own; a recording is uploaded only if you pick Send to Saved Messages for that specific recording. Recordings are deleted from the device when you delete them, when the account that made them logs out, and when the last account logs out.

Zenlygram Pro subscription

Zenlygram Pro is an optional auto-renewing subscription, bought through the App Store. It unlocks creating new items in Secret Vault, Chat Lock and Tasks, and showing the deleted messages and earlier message versions that the two features above keep; your vault, locked chats and tasks stay fully usable without it, and the kept messages stay on the device — behind a placeholder, never deleted — and are shown again when you subscribe. Your PINs and your hidden, locked, task and edit-history data never leave the device and are never sent to any server, subscription or not.

To know whether the subscription is active, the app talks to an entitlement server the developer operates. It is contacted when you link a Telegram account, when you buy or restore a subscription, and — once one of those has happened — about once a day in the background to re-check that the subscription is still active. It is never on the path of opening, unhiding, unlocking or reading anything you already have, and if you never buy and never link an account, it is never contacted at all. It receives:

• A random device identifier generated on this device at first use. It is not Apple's advertising identifier and not your device's serial number, and it identifies the app install, not you.
• A public key created in this device's Secure Enclave, used only to prove that later requests come from the same install.
• The device name, the app version and the iOS version, so the subscription page can tell your devices apart.
• Your Telegram user ID — only if you choose to link a Telegram account, which is optional; buying works without it. No phone number, no messages, no contacts.
• Your Apple push token, if push is registered, so the subscription state can be refreshed in the background.
• The App Store transaction receipt for a purchase, which Apple signs. Payment itself is handled entirely by Apple; the developer never sees your payment details.
• Your IP address, as with any request to any server on the internet. It is used to rate-limit abuse, is not used to build a profile or to locate you, and is discarded with the server access log.

This data is used only to decide whether Zenlygram Pro is active, and is not sold, shared for advertising, or used for tracking. If you never buy a subscription and never link a Telegram account, the app never contacts this server at all. Unlinking (Settings → Zenlygram → Telegram Account) ends the link; to have the records deleted, write to the address under Contact.

Translation and voice transcription

Messages are translated by the service you choose in Zenlygram settings under Translate Messages → Service. Quick Translate, the pinned-message bar, whole-chat translation and the translate option in the Send button menu (touch and hold Send to translate the text you are about to send) send the text only to that service. The Translate window (touch and hold a message → Translate, or select text in the message field → Translate) uses Telegram's translation, or Apple's on-device translation when System is selected. If the chosen service fails, the app shows an error (or no translation) and never switches to another service.

• Telegram (default): messages are translated by Telegram's servers under the Telegram Privacy Policy. Translating a whole chat requires Telegram Premium, except in channels whose owners enabled automatic translation; Telegram translates those automatically, as in the official app.
• Google Translate: the text of the messages you translate with Quick Translate, the pinned-message bar or whole-chat translation, and the text you translate from the Send button menu before sending it, is sent from your device to Google Translate (Google Privacy Policy). No message text is sent to Google unless you select this option. Whole-chat translation then works without Telegram Premium, but it starts only after you tap Translate, including in channels with automatic translation. The Translate window still uses Telegram.
• System (iOS 18 and later): the Translate window uses Apple's on-device translation, except for copy-protected messages, which use Telegram's translation with copying turned off. Quick, pinned-message, whole-chat and Send-menu translation use Telegram.

Messages in secret chats are never translated, including media captions and text recognized in photos. Copy-protected messages (for example, from chats that restrict saving content, including one-to-one chats where either person restricts saving) are never sent to Google.

Voice-message transcription uses Telegram's service or Apple's speech recognition — the latter when you select the system option, and always on accounts without Telegram Premium (Telegram's own transcription is Premium-only). The app requires Apple speech recognition to run on-device, so the audio is not sent to Apple. Both features run only when you invoke them, apart from Telegram's automatic translation of channels described above.

Auto-Proxy

If you enable the optional Auto-Proxy feature, your Telegram connection may be routed through third-party proxy servers to bypass network blocks. Proxy operators can see your IP address and the fact that you use Telegram, but not the content of your MTProto-encrypted traffic. This feature is off by default.

Sign-up verification (Google reCAPTCHA)

When you create a Telegram account in Zenlygram, Telegram's servers may ask the app for a sign-up check to confirm that a real person is registering. Only then does the app run Google reCAPTCHA Enterprise, which is part of the official Telegram app code. reCAPTCHA sends device and interaction signals (a device identifier, app performance data and interaction data) to Google. The resulting verification token goes to Telegram's servers, never to the developer. The app runs reCAPTCHA only for this sign-up check. See the Google Privacy Policy and Google Terms of Service.

Other connections and third parties

Besides Telegram, the app connects directly to the services below. Like any server your device connects to, they can see your IP address. The developer operates none of them and receives nothing from them.

• Google Translate: only if you select it as the translation service (see above).
• Google reCAPTCHA: only for the sign-up check (see above).
• Proxy servers: only if you turn on Auto-Proxy (see above).
• Foursquare's image server (4sqi.net): venue category icons load automatically when a chat or the location picker shows a place.
• Apple Maps: map previews for shared locations and the map in the location picker.
• Websites hosting content shown by inline bots, web documents or games: their images and media load directly from those websites when Telegram does not relay them.
• Websites you open: links you tap, embedded content in Instant View pages, players such as YouTube, and mini apps load from their own servers when you open or play them.

Link previews in messages are generated by Telegram's servers, not by your device. Apple speech recognition (voice-to-text) and Apple translation (the System option) run on the device.
