Privacy Policy

Last updated 23 August 2026

gramX has no servers of its own. Signed in or browsing as a guest, it talks to Telegram and to nobody else, and everything it keeps stays on your phone.

Who this is

gramX is an independent reader for Telegram channels, made by one person. It is not made by, affiliated with, or endorsed by Telegram.

Questions about this policy: daveyeinde@gmail.com.

Guest mode

You can read public channels without signing in. In that mode there is no Telegram account involved at all, and the app talks to Telegram over the ordinary web instead of through TDLib: for each channel you add, it fetches the public preview page at https://t.me/s/<channel> — the same page anyone can open in a browser — and reads the posts out of it.

Those requests carry what a browser request carries: your IP address, a browser user-agent string, and your device's language setting. They go to Telegram and to nobody else. The pictures on those posts are downloaded from Telegram's own servers and cached on your phone.

Guest mode is read-only. Nothing is sent on your behalf: no reactions, no comments, no read state, no subscriptions. There is no account for any of that to happen to.

What is stored is the list of channels you added, and the pictures cached for them. Leaving guest mode deletes both.

There is no gramX server

This app has no backend. When you sign in, the app connects straight to Telegram from your phone using TDLib, Telegram's own client library. Nothing you read, write or tap is sent to the developer or to any third party.

That also means Telegram receives what it would receive from any Telegram client — your account activity, the channels you read, the messages you send. That part is covered by Telegram's own privacy policy, not by this one.

What is stored on your phone

Telegram's local database of your chats, messages and downloaded media. It is encrypted with a 256-bit key held in your device's keystore, and it is what makes the app work offline.

A record of the signed-in account — your Telegram user id, display name, username, phone number and the path to your avatar — so the app can show whose feed it is showing.

Your bookmarks, as a list of chat and message ids. Each one also has a copy in your Telegram Saved Messages — see below — and that copy is what lets them survive reinstalling the app.

Your preferences: theme, autoplay, and which channels you have muted along with when each mute expires.

A short log of errors the app has caught — the last fifty, with phone numbers, file paths and keys stripped out before anything is written down. It is never shown to anyone and never sent anywhere; it exists so a bug you report can be looked into.

None of this leaves the device.

Keeping it safe

The local database is encrypted, and the key that opens it is held by your device's keystore rather than by the app. Someone with the files alone cannot read them.

Nothing gramX stores is unique to it: everything is a copy of what is already in your Telegram account, so losing the phone loses nothing that ending the session from another device does not protect.

What the app does to your Telegram account

This applies when you are signed in. In guest mode there is no account, so none of it happens.

This is a real Telegram client, so reading here changes things there. Specifically, gramX will: mark posts as read once they have been on your screen long enough, and that read state syncs to every device you use Telegram on; send the reactions you tap; post the comments you write; forward the posts you forward; subscribe you to a channel when you add one; and forward a post into your Saved Messages when you bookmark it, deleting that copy again when you remove the bookmark.

Read state cannot be undone. If you want the unread badges on your other devices left alone, do not read those posts here.

Your gramX session appears in Telegram under Settings → Devices, where you can end it at any time.

What the app never does

No analytics, no advertising, no tracking of any kind. There is no third-party SDK in the app that phones home.

No crash reporting service. The app keeps its own error log on the device so you can be asked what went wrong, and there is nowhere for it to send that log even if it wanted to.

Nothing is sold, shared or transmitted to anyone. There is nobody to transmit it to.

Media and link previews are fetched through Telegram, never from other hosts — so reading a post does not tell the website behind a link that you looked at it.

When you leave the app

Tapping a link in a post opens it in your browser. From that point you are on that website, and it can see your visit as any website you open would.

If you turn notifications on, your device shows them. Telegram decides what is worth a notification — a chat you muted there stays quiet here — and the text comes from Telegram; gramX only draws it. Notifications are off until you turn them on.

Settings has two links of its own — a way to support the work, and the source code. They open in your browser too.

Deleting your data

Logging out signs the session out of Telegram and clears the local account record, your bookmarks, and Telegram's local database.

Your preferences — theme, autoplay, muted channels — stay on the device until you uninstall the app.

The error log is deleted with the app's data when you uninstall it.

Settings → Media storage and cache clears downloaded media without signing you out.

Age

You need a Telegram account to use gramX, so you must be old enough to have one where you live.

Changes

If what the app stores or sends changes, this policy changes with it, and the date at the top moves. Continuing to use the app after that means the new version applies.
