Instant Completion Sync Both

When you complete a task on one device, TapTidy tells your other devices immediately. The moment the push message arrives, the task is marked done locally and any scheduled reminder for it is cancelled — so your tablet never buzzes for the prescription you already picked up. No extra network request is needed on the receiving device, which keeps this fast even in low-signal or battery-saving conditions.

It works on every delivery route

TapTidy delivers completion updates over whichever push transport your device uses, with identical behavior:

Verified, not just delivered

Every completion update carries a cryptographic signature from your account's signing keys. Your device verifies the signature before changing anything — a forged or tampered message can never silently complete a task or cancel a real reminder. This matters most on de-Googled phones, where push messages travel through third-party relay servers TapTidy does not control. Anything that fails verification is ignored, and the device simply performs a normal sync instead: the worst case is "slightly slower", never "wrong".

When the fast path steps aside

The instant path only applies changes it can apply safely. In every other case — an update for a task the device does not know yet, an out-of-date message arriving late, or an edit that changes more than the completion state — the device falls back to its regular synchronization, which reconciles against the server's authoritative state. Deleting a task always uses regular sync, since deletions cannot be safely replayed from a push message alone.

The Sync status line

Both apps show a quiet, four-state sync summary — in Settings → Sync on Android, and on the desktop toolbar sync button on the web:

Privacy

Completion updates contain only what the receiving device needs to apply the change safely: identifiers, timestamps, a version number, and the completed flag. Task titles, notes, and attachments never travel inside push completion messages. Optional, fully redacted sync-health diagnostics contain no task content either, use a temporary identifier that rotates every time the app restarts, and are pruned automatically (self-hosted operators control the retention window with TAPTIDY_RECEIPT_RETENTION_DAYS).
