Foliate 4. — the first minute without a single click
How we tested: a clean Debian 13 in a disposable container; source — package foliate 4.~really3.3.0-1 from the Debian repository. Run as a regular user on a virtual screen, 60 seconds, nothing clicked. 18.10.2026. Every network request and every file written was recorded; the code was not decompiled. The container was deleted afterwards.

| Google APIs | translate.googleapis.com | 1 |
Where it connected
Not a single request: no DNS lookup, no connection.

~/.cache/mesa_shader_cache_db | 102 |
~/.cache/dconf | 1 |
How to read this card
- This is the first minute after launch with no action at all: what the program does on its own. Normal use may involve more requests.
- A “built-in SDK” means the library’s code was found. It does not prove data transfer, and an address in the code is not a request.
- The review was made automatically using a single method. You can check any program yourself here.
