LuckgramPrivacy Policy
This policy explains what happens to your information when you use the Luckgram apps for iOS and Android and the luckgram.cc websites. Luckgram is an independent app built from the open-source Telegram apps.
Your Telegram data
Luckgram is a client for the Telegram network. When you sign in, send messages, make calls or sync contacts, the app exchanges that data directly with Telegram's servers. That data is processed by Telegram under the Telegram Privacy Policy, not by Luckgram.
Luckgram does not run its own servers for your messages, calls, contacts or media, and does not receive copies of them. The exceptions are the Luckgram features described in the next section, which only send data when you use them.
Luckgram features that use our servers
Some Luckgram features run on servers operated by Luckgram on Amazon Web Services in Singapore. Each feature can be turned off in Settings → Luckgram Features.
- Device registration. On first use the app registers an anonymous device token together with the platform, app version and language. We store only a hash of the token. A device that has not connected for 180 days is deleted.
- Account link. Features that need an account (AI quotas, People Nearby, Square, Luckgram Pro) link your device to your Telegram user ID through the Luckgram bot. We store only the numeric user ID, not your phone number. You can unlink in Settings → Luckgram Features → Account.
- AI features (assistant, summaries, writing help, reply suggestions, images, posts, voice-to-text and call transcripts). The text, audio or prompt you choose to process is sent through our server to OpenAI to produce the result, and is then returned to you. We do not store or log this content; we keep only usage records (feature, amount, time) for 90 days to enforce quotas. Generated images are kept for 24 hours so you can download them. OpenAI processes the content under its own terms. AI chat history is stored only on your device.
- People Nearby (only when you turn on “Visible nearby”). The app rounds your location to a grid of about 1 km on the device before sending it; your exact position never leaves the device. Your card (display name, bio, optional photo and public username) and that rounded location are deleted automatically after 24 hours, or immediately when you turn visibility off, sign out or unlink. Other users see only a distance range, never your coordinates.
- Square. Posts, comments and likes are public to all Luckgram users. Before upload the app resizes photos and removes their metadata, including GPS; videos are re-encoded without metadata. You can delete any post or comment, or remove all your Square data at once in Settings → Luckgram Features → Account. Media from deleted posts is removed within 24 hours, and all copies of deleted data within 30 days. Reported content may be reviewed and hidden.
- Square recommendations. To recommend Square posts you may like, Luckgram records how you browse and interact in Square: which posts you saw, how long you stayed, and when you open, like, comment on, share, report or mark a post “Not interested”. These records are linked only to an opaque device or user identifier, contain no post text and none of your chats, are used only to recommend and rank Square posts (including improving those recommendations), are not used anywhere else and are never combined with data from other apps or websites (no cross-app tracking). They are deleted automatically after 90 days.
- Luckgram Pro. Payments are made with Telegram Stars and processed by Telegram. We store your Telegram user ID and subscription period, not payment details.
- Settings, announcements and updates. The app downloads feature settings, in-app announcements and version information from our server. These requests carry only the device token and app version.
Server logs record technical details such as the request type, result and timing, never message, post or AI content, and are kept for 30 days. We do not sell your data or use it for advertising.
Data stored on your device
Like other Telegram apps, Luckgram keeps a local cache of your chats and media on your device so the app works quickly and offline. You can clear it in the app's storage settings, or remove it by uninstalling the app.
Analytics and advertising
Luckgram does not add analytics, advertising or tracking SDKs to the apps. Sponsored messages that Telegram shows in some public channels come from Telegram and follow Telegram's policies.
Services from Apple and Google
The apps use services built into the operating system or the Telegram code. Push notifications are delivered through Apple Push Notification service on iOS and Firebase Cloud Messaging on Android. On Android, maps and location features may use Google Play services. These providers process data under their own privacy policies.
Downloads
App builds are downloaded from dl.luckgram.cc. The files are stored with Amazon Web Services and delivered through Cloudflare, which may process technical data such as your IP address to deliver them. We don't keep download logs of our own.
Our websites
luckgram.cc and wiki.luckgram.cc are static websites hosted on GitHub Pages and served through Cloudflare. These providers may process technical data such as your IP address and browser type to deliver and protect the sites. The sites do not use cookies or analytics of their own.
If you write to a luckgram.cc address, we receive your email address and message and use them only to reply to you. Mail to these addresses is forwarded through Cloudflare Email Routing.
Children
Luckgram is not intended for children under the minimum age that Telegram requires in their country.
Changes
We may update this policy. The date at the top of this page shows when it last changed.
