Call Log Vault
Samsung only keeps your newest 2,000 calls? This offline vault saves all of them — no internet, no ads, and your backup stays in your hands.
Call Log Vault is an offline call-history vault for Samsung phone users: Samsung's built-in call log only keeps the newest 2,000 entries, and every new call quietly deletes the oldest one, with no warning and no setting to turn it off. This app copies every incoming, outgoing and missed call into its own on-device vault the moment the call log changes. The vault has no entry limit and never deletes anything on its own. Its main selling point is that it is offline all the way down: the app has no internet permission at all, and asks the system for only 4 permissions — reading the call log, writing the call log (for restoring), reading contacts (to show names), and starting after reboot. No ads, no root, no account, no trackers. It wakes only when the call log actually changes, copies the new calls and goes back to sleep, so battery use is effectively zero; a once-a-day safety sync catches anything that slipped through. Your backup stays in your hands: you can pick a folder of your own for automatic backups, stored as plain ZIP files containing CSV, JSON and XML, so clearing the app's data or uninstalling can never delete them; on a new phone you can import a backup and merge it without duplicates. When you want to restore, one tap writes your full history back into the system call log, visible in any dialer app; you can search by name or number, filter by call type, and view per-person timelines, in light, dark or true-black AMOLED themes. Three things to know: first, it is an Android app built around Samsung's 2,000-entry limit, so the limit rules on other brands may differ; second, if you restore more than 2,000 entries, the phone's own dialer will trim the oldest again over time, but the complete history in the vault is unaffected; third, as checked on 2 November 2026, the repo has 4 stars, 37 commits and 11 releases, is MIT open source, and its APK can be downloaded from the Releases page with SHA-256 hashes provided for you to verify.
