Where your data is stored
Halster stores records on your phone and uses EU storage for your account. The database is hosted in Ireland, the server in the Netherlands, and server files and backups in the EU. A backup file you save is stored wherever you choose to keep it. Email is handled by a provider in the US. The privacy policy explains which services process your data.
See where your data is processedKeep a backup
You can save a backup file from the app in a location you choose. After Premium ends, you can still view existing records and save a backup file. Storage remains subject to the account and data retention terms.
Get help with backupsAccount deletion
You can request account deletion in Halster. Save a backup file first if you want to keep one. The privacy policy explains how deletion and data retention are handled. Cancelling your subscription is a separate step.
How to delete your accountWhat we measure.
Halster measures app openings, screen visits and actions to improve the app and investigate problems. These measurements can be linked to your account. In Account → Data and privacy, turn off Usage measurement to stop measurement for your account and delete the usage data linked to it. For questions, email contact@halster.app. The website separately counts visits, download-link clicks and signup steps without linking those counts to a person.
