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. Settings page has an option to purge old reminders by clicking on the corresponding entry. This would delete all reminders that are older than 30 days and are in completed status. If it is a repeating reminder, then start date of the reminder would be updated and all the reminders that are older than that would be deleted. If the repeating reminder has an end time and that is older than 30 days, then that reminder is completely removed.

3. How does periodic purge from settings page work?
Ans. Periodic purge runs a background job once a day and removes all completed reminders that are more than 30 days old.

One-off reminder

            {
                "title": "Take laptop backup",
                "description": "",
                "recurrences": [
                    {
                        "startTime": "3 Jul 2023 05:13 PM",
                        "repeatInterval": 0,
                        "intervalUnit": "none"
                    }
                ],
                "reminders": [
                    {
                        "firstWhen": "3 Jul 2023 05:13 PM",
                        "when": "3 Jul 2023 05:13 PM",
                        "status": "completed"
                    }
                ]
            }
        

Recurrences have a startTime and an optional endTime. For one-off reminders, repeatInterval is 0 and intervalUnit is none.

Repeat reminders look like the below

        {
            "title": "Pick up milk",
            "description": "",
            "recurrences": [
                {
                    "startTime": "4 Jul 2023 01:00 PM",
                    "repeatInterval": 1,
                    "intervalUnit": "day"
                }
            ],
            "reminders": [
                {
                    "firstWhen": "4 Jul 2023 01:00 PM",
                    "when": "4 Jul 2023 01:00 PM",
                    "status": "completed"
                },    
            ]
        }
