Your data stays on your phone.
BodyCast is built privacy-first. There is no account to create, and the things that make BodyCast personal to you stay on your device. This policy explains, in plain English, exactly what that means.
BodyCast ("BodyCast", "we", "us") is made by The Yellow Labs. This policy covers the BodyCast mobile app and this website (getbodycast.com).
The short version
- No account, no sign-up.
- Your conditions, settings and feedback stay on your device.
- Your location is used only to fetch your local forecast — never tracked or stored by us.
- No analytics SDKs, no advertising, no cross-app tracking.
- The only thing we collect on a server is your email — and only if you choose to join the waitlist.
What the app stores on your device
The conditions you track, your sensitivity settings, your chosen location, any day-feedback you give, and your notification preferences are saved locally on your phone using the device's own storage. They are not uploaded to a BodyCast server — there is no BodyCast account system to upload them to.
Location
The app asks for "when in use" location access for a single purpose: to look up the forecast for where you are. We do not track your location in the background and we do not build a history of your movements. You can also enter a city by name instead of granting location access.
Weather & air-quality data
To produce your daily cast, the app sends your coordinates to Open-Meteo to retrieve weather and air-quality data (such as pressure, temperature, humidity, UV, rain, PM2.5, ozone and pollen). Open-Meteo processes that request under its own privacy practices; we send only what is needed to fetch the local forecast.
Notifications
Daily heads-ups and any "evening before" reminders are scheduled locally on your phone. We do not run a push server that watches you — your device decides when to show the notifications you opted into. You can turn them off any time in the app or your device settings.
This website & the waitlist
If you join our waitlist, we collect the email address you submit, for one reason: to let you know when BodyCast launches. We do not sell it or use it for unrelated marketing, and you can ask us to remove it at any time (see "Your choices" below). The site itself sets no advertising or tracking cookies. Our hosting provider (Vercel) may process standard server logs, such as IP addresses, to serve the site securely and reliably — this is typical of any website.
No tracking, no ads
BodyCast contains no analytics or advertising SDKs and does no cross-app or cross-site tracking. We don't sell or share personal data, because we don't collect it on a server in the first place (aside from a waitlist email, if you give us one).
Children's privacy
BodyCast is intended for adults, including parents and carers looking after family members. It is not directed at children under 13 (or the minimum age in your country), and we do not knowingly collect personal data from them.
Data retention & your choices
Because your app data lives on your device, deleting the app removes it. To remove a waitlist email, email us (below) and we'll delete it. You can revoke location or notification permissions at any time in your device settings.
Third-party services we use
- Open-Meteo — weather and air-quality forecasts (receives your coordinates to return a forecast).
- Vercel — hosting for this website (standard server logs).
- A waitlist/email provider for storing waitlist sign-ups (email only).
Changes to this policy
If we change how BodyCast handles data, we'll update this page and the "last updated" date below. Material changes will be made clear before they take effect.
Not medical advice
BodyCast forecasts weather-related trigger conditions. It is not medical advice and is not a substitute for professional care. Always follow your doctor's guidance.
