Auto-Remove Cached Media: Granular Retention Sliders, Chat Exceptions & Zero Local Bloat
Unlike legacy messengers that permanently clutter internal device storage with gigabytes of redundant video and photo files, Telegram operates as an infinite cloud-native messenger. Local files are treated as ephemeral cache — automatically purged based on category retention windows without ever deleting data from your chats.

Telegram Official Tip #101: Auto-Remove Cached Media and Granular Storage Usage

The Cloud Cache Paradigm: Ephemeral Local Files
Traditional messengers like WhatsApp store all media directly in device flash storage. If you clear space, you permanently delete the media from your chats unless backed up to third-party cloud storage.
In contrast, Telegram's TDLib storage engine decouples local disk usage from cloud permanence:

Permanent Cloud Anchoring
Every message, photo, 4K video, voice note, and document remains securely stored on Telegram's encrypted server cluster. Your local phone is strictly a temporary rendering cache.

Automated Category Expiry
Set independent retention sliders for Private Chats, Groups, and Channels (1 Day, 1 Week, 1 Month, or Never). High-traffic channels can purge daily while private family chats stay cached.

Granular Chat Exceptions & Max Cache Size Caps
In addition to blanket category rules, Telegram allows adding Individual Chat Exceptions:
- Family & Work Exceptions: Add your family group or direct project supervisor to Never Auto-Remove so high-priority documents and personal memories remain instantly accessible offline.
- High-Traffic Media Exceptions: Add 100k-member announcement channels or wallpaper groups to 1-Day Auto-Remove to prevent rapid cache accumulation.
- Maximum Cache Size Slider (LRU Eviction): Set total cache to 5 GB or 20 GB. If your phone nears this limit, TDLib automatically evicts the oldest, least-recently viewed media files.

Architectural Comparison: Telegram Cloud vs WhatsApp Local Storage
| Storage Vector | Telegram Cloud Cache Engine | WhatsApp / Signal Local Storage |
|---|---|---|
| Storage Model | Cloud-native cache (Disk is temporary) | Permanent local device storage |
| Disk Bloat Over 1 Year | Stays under 1 GB indefinitely via auto-purge | Bloats to 30 GB – 80 GB unless manually deleted |
| Device Migration | 0 MB transfer needed (Instant cloud sync) | Requires massive gigabyte backup archives |
| Cache Purge Safety | 100% Safe (1-tap re-download from cloud) | Destructive (Deleted files vanish forever) |
