GRAVITY · BIORHYTHMS

Privacy policy

Your information stays on your device.

Updated October 11, 2026

01

About the app and this policy

gravity tech develops the standalone Android app Biorhythms, package com.gravitytech.biorhythms. This policy covers only this biorhythm app and does not describe other Gravity apps.

02

All information stays on your device

We do not collect or receive data from the app, or store it on our servers. The name, surname and birth date you enter are stored only in the app’s private local storage on your device. Biorhythm calculations run on the device. These details are not sent to the developer or third parties.

The profile is used to display information and perform calculations. There is no online registration or cloud synchronization. The app configuration disables cloud backup and standard Android device transfer of the profile.

03

Analytics and data transfers

The app operates without internet access and uses no analytics, advertising tracking or crash-reporting SDKs. It does not collect usage information, advertising identifiers or location, or transmit your profile to servers. We do not sell or share data from the app with third parties.

04

Storage and deletion

Your local profile remains until you clear app data or uninstall the app. You can edit the information in the app. To remove all local data, open Android Settings → Apps → Biorhythms → Storage → Clear data / Clear storage, or uninstall the app. Labels vary by device.

We cannot access your local profile and cannot view, recover or delete it remotely.

05

Contacting support

For privacy questions, email gravitylogy@gmail.com. If you choose to send an email, we receive your sender address, message and any attachments to answer your inquiry. This is separate voluntary correspondence, rather than data collection by the app. Do not send your birth date or other personal details unless needed for your question.

06

Opening this page

This page has no forms, analytics or advertising trackers and does not request your app profile. When you visit the website, the server receives technical information needed to deliver the page, such as your IP address and requested URL. This concerns the website visit rather than app use; the app does not send profile details or calculations here.

07

Changes and questions

The date at the top identifies this policy’s revision. If data handling in the app changes, this policy will be updated to explain the new practices. Send questions to gravitylogy@gmail.com.
