A local project keeps the editable calendar in the browser and device you are using. It is not an account, cloud backup or synchronization service. Download a JSON backup when you want a separate copy that you can keep or restore elsewhere.
Save and check the result
Use Save project and choose a recognizable name. Check the save result before leaving the editor. A successful local save makes the project available from My projects in the same browser context. If the action reports a storage problem, the calendar is not safely stored just because it remains visible on screen.
Keep the current editor open while you download a JSON backup after a save failure. The backup contains the editable project rather than only its printed appearance. PDF and PNG are useful for viewing or printing, but they are not a substitute for the project file when you want to revise its events and layout.
Reopen and identify the right project
Open My projects and choose the calendar you want to continue. Review its name, layout and date range before editing. A list can contain similar copies, so a name such as “2027 family calendar” is more useful than several projects all called Calendar.
If the list is empty, check that you are using the same browser and device as before. Browser-local data does not automatically follow you to another computer or profile. Clearing site data or ending a private-browsing session can remove access to saved local projects.
Duplicate or rename before a major change
Use the copy action when you want a separate version of a calendar. Rename that copy so it is clear which project you are editing. A duplicate lets you try a different layout or prepare a new year while retaining the original project.
Review dates when reusing a calendar for another year. A copied event may still refer to its original date, and an optional holiday collection has its own reviewed coverage. Reusing a style does not make every old appointment appropriate for the new range.
Download and restore a JSON backup
Download the project JSON and keep it in a location you can find again. Read the file name and date so you know which version it contains. Before moving devices or clearing browser data, make sure the backup you need has actually been downloaded.
To restore, choose the MonthSprig JSON import and review the project before confirmation. If the file is damaged or uses an unsupported version, keep the existing project unchanged and choose a valid backup. Do not treat an error as a successful restoration simply because some file text can be read.
Delete only the copy you intend to remove
Check the project name before using its delete action. Deleting a local project removes that saved copy; it does not remove PDFs, images or JSON files already downloaded to your device. Those files are managed separately through your device’s file storage.
MonthSprig cannot promise recovery of a browser-local project after its data has been removed. Keep a separate backup for work you need. If local saving is blocked by browser settings or available storage, continue only while you can preserve the current work in a downloaded project file.
