JetGuide

JetGuide builds a personal jet lag plan timed to your body clock. It is designed to work offline and to keep your personal and health data on your device. We do not sell your data, and we never use your health data for advertising.

What you enter: trips and profile

The trips you create — flights, dates, destinations — and your profile, including your usual bed and wake times, your chronotype answers, and your preferences, are entered by you and used only to generate and display your plan. They are stored on your device.

Health data from Health Connect

With your permission, JetGuide reads your sleep and your heart rate from Health Connect. It uses them to estimate where your body clock actually is and to adjust your plan to match, instead of assuming a schedule.

This data is read with your permission, processed on your device, and never transmitted to us. It is never used for advertising and never sold. You can revoke the permission at any time in Health Connect settings.

Location

The Android app does not collect location. It holds no location permission, keeps no location history, and sends no location anywhere.

Flight lookups

When you look up a flight, the flight number and date you entered are sent to AeroDataBox to retrieve the flight's times. No health data, name, or account identifier is sent with that lookup.

Purchases

If you buy Premium, your payment is processed by Google Play under Google's own privacy policy. Our subscription provider, RevenueCat, receives purchase metadata and an anonymized subscriber ID so the app can unlock Premium features. We do not receive your payment card details.

Diagnostics and app improvement

JetGuide can count which features get used and where its recommendations miss the mark, and it can send a crash report when the app fails. This counting is on by default; you can turn it off at any time in the You tab under "Help improve the app," and once it is off nothing more is counted or sent. Reports go to our own server over HTTPS and carry a random install ID — no account, no advertising ID, and no name. They never include your sleep or heart-rate data or your trips, and no location more precise than the city level. Feedback you write inside the app is sent only when you tap Send.

What we do not do

• We do not sell or rent your personal or health data.
• We do not use health data for advertising, marketing, or data mining.
• We do not require an account to use the app.
• We include no advertising SDKs and no third-party trackers. The only counting is the first-party diagnostics described above.

Security

The network requests the app makes — flight lookups, purchase validation, and the diagnostics described above — are encrypted in transit over HTTPS.

Retention and deletion

Data you enter lives on your device and is removed when you clear the app's data or delete the app. Health permissions can be revoked at any time in Health Connect settings. Diagnostics and crash records are tied only to a random install ID; contact us and we will delete the records associated with it. To ask about data associated with your subscription ID, contact us at [email protected].

Children

JetGuide is not directed to children under 13 (16 in the EEA), and we do not knowingly collect their data.

Your rights

Depending on where you live (for example under GDPR or CCPA), you may have rights to access, correct, or delete your data. Contact us at [email protected] and we will help.

Medical disclaimer

JetGuide provides wellness and behavioral-timing guidance only. It is not medical advice and is not a substitute for professional care. Consult a clinician before using melatonin or making changes if you have a health condition.

Changes to this policy

If we add account sync or ads in the future, we will update this policy and the store disclosures before shipping that change. Updates will be posted here with a new effective date.
