Privacy Policy
Packnroll (“the app”, “we”, “us”) is built to need as little of your data as possible. This Privacy Policy explains what information the app does and does not collect, how it is used, and the choices you have. By using the app, you agree to this policy.
Information stored only on your device
Your trips and everything about them — trip names, destinations, dates, who's travelling, your packing lists, which items are packed, whether you have them at home or need to buy them, and any notes — are stored locally on your device only. This information is never uploaded to our servers, we cannot read it, and it is never included in analytics. Deleting the app removes this data from your device.
Information sent to generate a packing list
When you ask for a packing list, the app sends a minimal, de-identified request to our backend so it can generate suggestions with the help of an AI model. This request contains only the destination, travel dates, the number of adults and children, the trip type, transport, luggage type, and your device locale. Your trip name and any free-text notes are never sent. These requests are used solely to return a packing list and are not used to identify you or to build a profile of you. The AI processing is performed by our backend and by our model provider (Google's Gemini API) acting on our behalf.
Anonymous device identifier
To prevent abuse and apply fair rate limits, requests include an anonymous identifier derived from your device's vendor ID, together with an anonymous Firebase authentication token. This identifier is not linked to your name, email, or any personal account, and is not used for advertising. Reinstalling the app resets it.
Analytics and crash reporting
We use Google Firebase (Analytics and Crashlytics) to understand how the app is used in aggregate and to diagnose crashes, solely to improve reliability and the experience. These events are anonymized and are not linked to your identity.
No ads and no tracking
Packnroll does not show ads, does not sell your personal information, and does not track you across other companies' apps or websites. The app contains no advertising or attribution SDKs and does not use the advertising identifier (IDFA), so it never shows an App Tracking Transparency prompt.
Amazon Associates
Tapping an item you need to buy opens an Amazon search page in your browser that includes our affiliate tag. Anything you do on Amazon — browsing, signing in, or purchasing — is governed by Amazon's own privacy policy, not ours. As an Amazon Associate, we may earn a commission from qualifying purchases, at no extra cost to you.
Data retention
On-device data stays on your device until you delete it or remove the app. De-identified packing-list requests and aggregated analytics data are retained only as long as needed for the purposes described above, and are then deleted or kept only in aggregate form.
Your choices
You can reset the anonymous identifier by reinstalling the app, and remove all on-device data by deleting the app. For any question or request about your data, contact us using the details below.
Children
The app is not directed to children under 13, and we do not knowingly collect personal information from them. If you believe a child has provided us with personal information, please contact us.
Changes to this policy
We may update this policy from time to time. The “Last updated” date above reflects the latest version, and your continued use of the app after changes take effect constitutes acceptance.
