Your home stays off the map. A privacy zone hides the 200 m around it from every shared map — on by default, for everyone who isn't you.
Photos lose their location. Location data is stripped from every photo before it leaves your phone.
Plain-language privacy. Every setting explains itself in one sentence.
You choose who sees each run. 🔒 only you, 👥 followers, or 🌍 everyone — chosen explicitly at sign-up, changeable per run.

Inertial.run is made by Parth Dixit, an independent developer in India ("we"). This policy covers the Inertial.run app for iPhone, Apple Watch and Android and the services behind it. Questions, requests and complaints go to safety@inertial.run.
| Data | Why we use it |
|---|---|
| Account: your name, email address or phone number, from the way you sign in (Apple, Google or a phone code) | To create your account and keep it secure |
| Waitlist: your email, a WhatsApp number if you add one, which link brought you, and whether you're bringing runs from another app | To confirm you joined and tell you when your spot opens |
| Profile: handle, display name, profile photo, privacy settings, and confirmation that you are 18 or older (not your date of birth) | To show your profile to the people you allow |
| Runs: GPS route, time, distance, pace, splits, elevation, titles and notes | To record, save and show your runs |
| Heart rate (optional): read from Apple Watch through Apple Health, only if you allow it | To show your heart rate during a run and save its average with the run |
| What you post: photos, stories, comments, cheers, follows, reports and blocks | To share with the people you choose and keep the community safe |
| Imports and connections (optional): a data export you upload, or access to another running service you choose to connect | To bring your past runs in. Disconnect any time |
| Anonymous usage events: for example "a run was saved", with a random device ID, run duration and distance. Never your route, location, name or account | To learn which features work. Not linked to you |
| Crash reports: device model, system version and the error. Never coordinates, handles or sign-in tokens | To fix crashes. Not linked to you |
We do not collect your contacts, your advertising identifier, your browsing history or payment details. We do not sell your data, show ads, or track you across other apps or websites.
These companies process data for us only to run their part of the service. Some are outside India, including in the United States.
Inertial.run is for people aged 18 and over, and sign-up asks you to confirm your age. We do not knowingly collect data from anyone younger. If we learn we have, we delete it.
Data travels over encrypted connections. Database rules let only the people you allow read your data, and photos load through short-lived links.
When this policy changes, we update this page and the date at the top. We tell you in the app about any change that affects how your data is used.
