Personal software, one user
A small script that keeps one person's Apple Reminders and Google Tasks pointed at the same list.
Reminders Sync is a personal automation tool written and run by its own developer, Sam Morris. It keeps a small set of Apple Reminders lists in two-way sync with matching Google Tasks lists, so an item added, completed, or edited on one side shows up on the other — across a Mac laptop and a Mac mini, both belonging to the same person.
It is not a public product. It has exactly one user, is not distributed or offered to anyone else, and has no sign-up flow — the Google account it connects to is the developer's own.
Last updated alongside the tool itself. Since there is one user, this describes exactly what happens to that one person's data — nothing more general.
tasks scope of the Google Tasks API.Data read from either side is written to the other side, and nowhere else. A small local database (SQLite) tracks which reminder corresponds to which task so the sync can detect edits, completions, and deletions on subsequent runs.
Entirely on the developer's own Macs. The Google account tokens, the local sync database, and all synced content live in a private folder on each machine. Nothing is uploaded to any server other than Google's own Tasks API endpoints, which the sync talks to directly using Google's official client library.
Access can be revoked at any time from Google Account › Security › Third-party access. Deleting the local application folder removes every trace of the sync from a given machine.
Reminders Sync is provided by its developer for the developer's own personal use only. It is not offered, licensed, or warranted to any other party.
