    Good day. Love your app, I’ve been using it for years, but the latest version keeps crashing when I try and open it. I think it might have a bug. Please fix this problem.
    Thank you!

    You should make this compatible with the Health app on the iPhones

    Hello! I use My days X app for many years, and I try to open it today and it crashes. When I open it, the screen gets black and it returns to my home page. What can I do? I don’t want to delete and reinstall the app, because that way I’ll lose all of my period data (I haven’t done any backup before)
    Please help me!
    Thank you!

    I had this app for like 3 maybe 4 years up until earlier this year. I had to reinstall the app and all my data is lost. I remember I had to input my email address to use this app before. Now I did the same and I’m pretty sure I am on this app like a new user. Why? I have no data from before I had to reinstall.

      Posting this because apparently I have to to use now? Fine
      I do like the app and have been using it for years but now I wish I could just move my info to something else. The ads are annoying and intrusive with many forced to play through and why does it suddenly need access to my location just so I can check when my period is due? And why does it ask repeatedly?

      Hi there,

      MyDays X does offer you a Backup Feature via the MyDays Server.
      Without a proper Backup, you will loose all your Data while a factory reset, loosing or damaging your mobile.

      To backup your data and also send it to another device or new app:

      SAVE your Data.
      1. Goto MyDays X “Settings/Backup via MyDays Server”
      2. Enter your eMail and a random BackupId (remember this BackupId for later Restore)
      3. Click UPLOAD ! (You will get a warning if there is former Backup on the server with same Backupid)

      RESTORE your Data.
      1. Goto MyDays X “Settings/Backup via MyDays Server”
      2. Enter ur eMail and the same BackupId you used before to save your Data.
      3. Click “RESTORE” (do not click -upload- as this would overwrite your data on the Server)

      Thats it!

      Here some additional Advice
      to feel safe your Data will never be lost.

      Sometimes we all make mistakes and forget to backup, delete/overwrite our Backups with wrong Data or even a technical issue happens.
      So I its also a great Idea to have a Backup via eMail thats in your private eMail Account.

      To cover all that. here some Tips:

      A. Set ‘AUTO-BACKUP” every 5 Days (in Settings/Backup via MyDays Server at the Bottom, do not set SYNC if you don’t need)
      B. Do sometimes a manual Backup with a different BackupId
      C. Do sometimes a manual Backup via “Settings/Other Data Backup Options/Backup via eMail”. This eMail Backup cam be restored via “Settings/Other Data Backup Options/Backup via Wifi”

      About Syncing Data with another Device or your Partner.
      You find this Feature in
      “Settings/Backup via MyDays Server at the bottom within the Auto Backup Feature”

      Is a nice thing to share data with your Partner on another Device.
      Also Syncing can be a tricky process.
      Therefor better do also a backup from your data before that process with a different backupid so you have a backup that can not be overwritten by accident. Depending on a good and stable Internet Connection there is no guarantee that Sync always works as it should.

      How Sync does work:
      When you close the App the App will check if the Data from your Devices is already on the MyDays Server. If not, it will upload it.
      When you open the App it checks if there is a different Version on the Server and download it if its newer.

      How to recover a BackupID you used before.
      Should u ever made a Backup via MyDays Server and forgot your BackupID

      1. Goto “settings/backup via mydays server”
      2. Enter your email and click the [?eMail] Symbol beside the eMail Field.
      Now all the BackupIds associated with your eMail will be sent to your email.

      I really care about that you feel sound and safe.

      Hope that helps

      all the best
