Sip is a quiet app. It keeps to itself.

Effective 5 May 2026 · Last updated 5 May 2026

Short version: Sip helps you build a caffeine habit that fits your day — and your sleep. To do that, it stores everything on your device. Nothing is collected, sent off, shared, or sold. There are no accounts, no analytics, no advertising, and no third-party SDKs. If you delete the app, your data goes with it.

1. What information Sip collects

None, in the sense that we never receive any of it. The app keeps a local record of the things you tell it about yourself and your routine, so it can model when caffeine is wearing off in your body. Concretely:

Each sip you log — drink name, milligrams, ounces, time
Your regulars — drinks you pin for one-tap logging
Your weight, sensitivity, and bedtime, from onboarding
Display preferences: weight unit (kg / lbs), hero style, daily ceiling toggle

This information lives on your device, in a local SQLite database inside the app's sandbox. Sip has no servers. There is no account to create, no email to enter, no profile to maintain.

2. How data is stored

All data lives in an on-device file managed by the operating system's app sandbox. iOS or Android backups (such as iCloud Backup or Google One Backup) may include the app's data in their normal device-level backups if you have those enabled — that is governed by Apple's or Google's privacy practices for those services, not by Sip.

3. Permissions Sip requests

Sip declares no Android permissions and no iOS usage descriptions. It does not access the camera, microphone, location, contacts, photos, or notifications.

4. Network usage

Sip performs no network requests. It does not contact any server, download remote content, or report errors home. The app functions identically with or without an internet connection.

5. Third parties and analytics

Sip uses no third-party analytics, no advertising SDKs, no crash reporters, no A/B-testing tools, and no marketing trackers. It contains no embedded web content from third parties. The only outside code in the app is the open-source Flutter framework and a small number of widely-used, non-network packages used to read and write the local database, format paths, and trigger the system Share sheet.

6. Sharing your data

If you tap "Export" inside the app, Sip generates a CSV file of your sips and hands it to your operating system's standard Share sheet. Where it goes from there is your choice — email, AirDrop, a notes app — and that destination's privacy practices apply once the file leaves Sip.

7. Children

Sip does not knowingly collect any data, including data from children, because it does not collect data at all. The app is rated for general audiences but contains no information collection mechanisms that would implicate COPPA, GDPR-K, or similar regimes.

8. Your rights and your data

Because all data is stored locally on your device, you control it directly. You can edit or delete any logged sip from the History screen, reset settings from the You screen, or delete the app to remove all Sip data from your device.

We do not have your data on any server, so we cannot honor a "right to access" or "right to delete" request — there is nothing on our end to access or delete.

9. Changes to this policy

If the app's data practices ever change — for example, if a future version adds an optional cloud sync — this page will be updated and the app will surface the change before any new behavior takes effect.
