FAQ

1. As Reminder Mate is offline, do I need to take regular backup of data?
Ans. Android settings has device backup feature. This regularly backs up apps on the device (usually on a daily basis) and backs up Reminder Mate data as well. This should be sufficient for most usecases. You can also do a manual backup of Reminder Mate data through settings page of the app and use it to restore reminders later.

2. How does purging old reminders from settings page work?
Ans. Reminder mate would delete periodically reminders that are in completed state for more than 30 days. This would ensure that number of reminders does not increase to slow down the app. Any reminder with start date of more than 30 days would have their start dates changes so that they are within 30 days.

Data Backup Format

Data is saved in gzipped JSON format when you do a backup from settings page. File has the following format remindermate_<yyyyMMddHHmm>.json.gz. Eg. remindermate_202307122102.json.gz.

Content has an array of reminders and actions similar to the following.

One-off reminder

        {
            "reminders": [
                {
                    "id": 1,
                    "title": "Take laptop backup",
                    "startDateTime": "2025-12-25T09:35:00"
                }
            ],
            "actions": [
                {
                    "reminderId": 1,
                    "originalScheduledTime": "2025-12-25T09:35:00",
                    "type": "COMPLETED"
                }
            ]
        }    
        
        

Recurrences have a startDateTime and an optional count. SNOOZED reminders have rescheduledTime in their actions.
