Data stored on your device
The app stores workspace settings, service names and entered business values, ordering, confirmed current prices, and saved audit snapshots in its local app container. Menu Change Plan drafts exist only in memory while the editor is open and are not persisted. Confirmed changes and their exact before-and-after audit pair are saved atomically. These values calculate and display estimates on your device.
Trest Line OÜ does not receive this working data. Apple-controlled device backup may process app data according to your Apple and device settings.
Purchases
Optional purchases are processed by Apple through StoreKit. We do not receive your payment credentials. Apple may process purchase and account data under its own terms and privacy policy.
Sharing and external links
When you explicitly copy or share text, CSV, or PDF output, the system service or provider you select may process it.
Website hosting and security services may process an IP address, request headers, URL, time, and similar technical data, and may set a strictly necessary security cookie such as __cf_bm to protect the site. Marginelle does not use it for advertising, analytics, or cross-site tracking.
Retention and deletion
Local data remains until you delete records or remove the app, subject to Apple-controlled backup behavior. Marginelle has no developer account data to delete. Exported files may remain wherever you chose to save or share them.
Support email
If you email support@trestline.app, the email provider processes your address, message, and attachments so Trest Line OÜ can respond. Send only the minimum non-sensitive information needed.
Support correspondence is retained only as reasonably necessary for the request, legal obligations, and abuse prevention.
