wtf is phone-record-manager?

Phone Record Manager is a desktop application for Windows that helps someone keep track of which phone numbers are linked to which website and app accounts, so they can manage the manual process of replacing a phone number across many accounts. It is built with Python, the PySide6 interface library, and a local SQLite database, and everything is stored on the user's own machine rather than in the cloud. The application does not automate logging into other services, submitting verification codes, or bypassing any security checks. Instead, it functions as a structured checklist: a user records each phone number, its current status such as active or being replaced, and a list of the websites and apps tied to it. When it is time to switch a number, the user creates a replacement task, and the application tracks each account that still needs to be manually updated, preventing accidental edits to accounts already involved in an active replacement. Other features include a master-password login using a standard password-hashing method, an idle-lock timer, light and dark themes, both Chinese and English interfaces, CSV import and export, and encrypted backups using a well-known Python encryption library. Restoring a backup checks the data's structure and internal rules before replacing anything, all inside a single database transaction so a failed restore cannot leave the data half-written. The README is direct about a security boundary: the master password only controls access through the application interface, it does not encrypt the underlying database file, so anyone with direct access to that file could still read its contents. The project targets Windows only, requires Python 3.12 to run from source, and ships prebuilt release packages including an installer, though the release is not code-signed. It is released under the MIT license.
