Storage warnings
If Latr says it cannot save something, it is almost certainly thumbnails. They are the only thing in the product large enough to fill anything, and turning them off frees the space immediately.
The fix, first
Settings → Appearance → turn off page thumbnails. Then Settings → Your Data, where you can clear the ones already stored.
That is the answer for nearly everybody, and it does not cost you a single reminder — thumbnails are a convenience for telling similar titles apart, nothing more.
What actually takes up room
| Thing | Roughly |
|---|---|
| A reminder | A fraction of a kilobyte. Text. |
| A page thumbnail | 12–40KB each |
| An uploaded sound | Up to 1MB, twelve maximum |
| Your settings | Negligible |
A thousand reminders is a rounding error. A thousand thumbnails is tens of megabytes. That ratio is why thumbnails are stored under their own keys and only loaded when the popup actually draws them — so the rest of Latr never pays for them either in space or in speed.
Two different limits
There are two, and the message tells you which one you met.
- Local storage on this machine. Latr asks the browser to lift the default cap, so this is rarely the one you hit — but a very large number of thumbnails can still get there.
- Sync storage, which is much smaller and shared with everything else your browser syncs. This is the one people meet.
When Latr cannot write something it says so and names the setting that would free space, rather than failing quietly. A silent write failure would mean a reminder that appears to save and never fires, which is the one failure this product cannot have.
If the message mentions sync
Sync storage is a small allowance — around a hundred kilobytes in total, with a per-item limit of about eight. Your reminders themselves are text and fit comfortably; what pushes it over is usually accumulated history and settings on an install with a great many reminders.
Your local reminders are untouched when a sync write fails. Nothing is lost; the copy on this machine is complete and it is only the copying that stopped. Options:
- Clear out reminders you no longer need
- Turn sync off and move things with a backup instead
- Reduce how long fired reminders are kept
General housekeeping
- Export before you clear anything. A JSON backup takes one click and means a deletion you regret is recoverable.
- Look at what is actually there. A CSV export sorted by date usually reveals a few hundred reminders from an import you no longer care about.
- Bulk select is your friend. Filter the queue by tag, folder or site, select all, and delete in one go — with one undo covering the lot.
