A date list can contain more personal information than it first appears. A name paired with a full date of birth, a family note, or a guest list may be sensitive. Keep what you actually use, then protect the copies you create.
Store the minimum you need
Use a first name or nickname where it is enough to recognize the event. Leave the birth year blank when you only want an annual birthday. Keep payment details, health information, and access codes elsewhere. The site stores records in IndexedDB in the current browser and does not automatically send them to a server. Browser storage does not by itself promise encryption.
Make a backup you can find
- Open the exporter and choose All dates.
- Export JSON and give the file a recognizable date in its name.
- Keep it in a location you control, with access appropriate to the notes it contains.
- Create another backup after major edits or before changing devices or clearing browser data.
- Retain an older copy until you confirm that a newer backup has the records you need.
Know what restore replaces
Suppose your current browser contains six dates and two plans and an older backup contains four dates and one plan. Restoring that older backup leaves four dates and one plan, because restore replaces the collection. Download the current data first if you may want to recover it. A malformed or unsupported backup is rejected before replacement. Review the item counts in the confirmation prompt.
Treat copies as separate data
Deleting a birthday from the tracker does not remove it from downloaded files or from another calendar where you imported it. If you are cleaning up a sensitive record, review those copies too. When switching browser profiles, make sure you can open the file from the destination profile before clearing the old one.
FAQ
Can I restore from CSV or ICS?
Use the versioned JSON backup to restore. CSV and ICS serve different destinations and do not preserve every field.
What happens if I clear browser data?
Your local records may be removed. A complete JSON backup is how you can restore them.
