Privacy Policy
Last updated: 7.8.2026
Hi! This page explains how Cycling Data Lab handles your data. I built this app to help cyclists work with their performance numbers, and I take your privacy seriously.
What Information Do I Collect?
Personal Information
When you create an account, I collect:
Your email address
Your phone number (if you choose to provide it)
Usage Data
The app automatically collects some technical information to help me keep things running smoothly, like:
Your IP address
Browser type and version
Pages you visit and when
Device information (if you're using a mobile device)
Cookies
I use essential cookies to keep you logged in and make the app work properly. These are necessary cookies - without them, you wouldn't be able to use the app effectively.
Public Share Cards
If you choose to create a share card, I store the title you enter, the displayed calculation summary, chart points, creation time, and the number of times its public link is opened. Share cards do not include your rider weight, FTP, W', email address, or route coordinates. Anyone with the link can view the card, so do not put private information in its title.
How Do I Use Your Data?
I use your information to:
Run the app and provide you with the calculators and tools
Manage your account
Contact you about important updates or security issues
Respond to your questions or requests
I will never sell your data to anyone.
How Long Do I Keep Your Data?
I keep your personal data as long as you have an account. Usage data is kept for shorter periods, unless I need it for security or to improve the app.
Your Control Over Your Data
You have full control over your data:
Download your data: You can download everything from your account page.
Delete your account: You can delete your account and all your data anytime from your account page. This is permanent and can't be undone.
Security
I do my best to protect your data using industry-standard security measures.
Changes to This Policy
I might update this policy occasionally. If I make significant changes, I'll let you know by email or with a notice in the app.
