Account & Data Deletion

About this page

This page explains how to request deletion of your Mara account and any data Mara stores about you. Mara is a personal logging tool for breastfeeding, pumping, diapers, and baby weight, developed by Alexandru Romanescu.

What data Mara stores

If you only use the app locally (no sync):

All your data lives on your device only. Mara does not store any of your data on a server. To delete it, simply uninstall the app or use Settings → Data → Reset all data.

If you use Mara Cloud sync:

• Email address (for account authentication)
• Device identifiers (for sync pairing)
• Caregiver name (if provided)
• Baby tracking data: feeding sessions, pumping volumes, diaper changes, weight records, supplement logs

How to request deletion

To request deletion of your Mara Cloud account and all associated server-side data, send an email to privacy@knowbs.eu from the email address registered on your Mara Cloud account.

In your email, please include:

• Subject: Mara account deletion request
• The email address of the account to be deleted
• Whether you want to delete the entire account, or only specific data (specify which)

We will confirm receipt within 7 days and complete the deletion within 30 days. You will receive an email confirming the deletion has been performed.

What gets deleted

• All baby tracking data stored on the Mara server
• Your account record (email, device IDs, caregiver name)
• Family membership and any active partner-share invites
• Subscription record (your Google Play subscription itself must be cancelled separately via the Play Store)

What is kept (and for how long)

• Encrypted backups: Server backups may contain your data for up to 30 days after deletion before they are overwritten.
• Email logs: The email exchange about your deletion request itself is retained for 1 year for audit purposes (GDPR Article 30).
• Local data on your device: Account deletion does not affect data stored locally on your device. Uninstall the app or use Settings → Data → Reset all data to remove local data.

Cancelling your subscription

Account deletion does not automatically cancel your Mara Cloud subscription. To cancel billing, go to Google Play subscriptions and cancel Mara Cloud.

Partial deletion

You can also request deletion of specific data without closing your account — for example, deleting all sessions before a certain date. Use the same email address above and describe what should be deleted.

Alternatively, you can stop server-side processing at any time without contacting us by disabling sync in the app: Settings → Sync → disconnect. This stops new data from being sent to the server. To delete what is already on the server, contact us.
