What is inside
Built for runners who
read maps like scoreboards
Fog of war
The city map is sliced into 100×100 m sectors. Run through a new one and the fog lifts for good.
City percentage
Watch your explored share of the city grow, district by district, with a clean running total.
Split calculator
Pick a target from 5K to the marathon and get even-pace splits and finish projections.
Cadence & stride
See steps per minute and stride length for every run, and tune your rhythm over time.
Karvonen zones
Heart-rate zones computed from your resting and max values, not a one-size-fits-all guess.
Shoe odometer
Log kilometres per pair and get a nudge as wear approaches the 500–800 km window.
Coverage journal
A running log of every newly cleared area, so you can revisit where you have been.
Progress charts
Weekly distance, pace and coverage trends drawn right on your device.
Fully offline
No sign-in, no servers, no sync. The app works in a tunnel, on a trail, or in airplane mode.
Split planner
A taste of the in-app calculator. Choose a race and goal time.

About Us
The people
behind the fog
🏃 We are a small crew of runners and map nerds who got tired of the same five loops. GridRun grew out of a simple itch: what if every unfamiliar street was a square waiting to be unlocked?
🗺️ Our mission is to make exploring your own city as addictive as chasing a personal best, while keeping every route and every heartbeat on your own phone.
🧭 You get a living map of your progress, honest training tools for pace, cadence, heart-rate zones and shoe wear, and a reason to turn left when you would normally turn right.
👟 The value is freedom: a running companion that needs no account, no signal and no trust. It simply helps you go further and see more.
Clear the fog. Own the grid.

Privacy Policy
Effective Date: October 2026
GridRun: Sector Conquest is built to work entirely on your device. We do not collect, store, or transmit your personal data, and your routes and location never leave your phone.
1. Information We Collect
None. The app does not collect personal information, location history, routes, heart-rate values, shoe records, or device identifiers. Location is used on the device only to reveal map sectors while you run.
2. How We Use Information
We do not use, analyze, profile, or sell any information about you, because we never receive any. Calculations such as splits, cadence, and Karvonen zones happen locally.
3. Data Storage
Everything you create, including explored sectors, the coverage journal, training stats, and shoe mileage, is stored only on your device. There is no cloud storage and no backup server on our side.
4. Third-Party Services
The app contains no analytics, advertising, or tracking components, and does not share data with any third party.
5. Data Security
Because data stays in the app's local storage and is never sent over a network, it is protected by your device's own security, such as your passcode and system encryption. We encourage you to keep your device locked and updated.
6. Children's Privacy
We collect no data from anyone, including children under 13, which keeps the app in line with the spirit of COPPA. Young runners should still be supervised when running outdoors.
7. Your Control
There are no accounts to manage. You are in full control: deleting the app removes all of its stored data from your device.
8. Changes to This Policy
If this policy changes, the updated version will appear here with a new effective date. Our commitment to local-only data will not change quietly.
