Summary
You can use every calculator on GrowLytics Run without creating an account or giving us personal information. The values you enter into calculators are processed in your browser and are not sent to or stored on our servers.
Information we collect
- Server logs. Like most websites, our web server automatically records technical information such as IP address, browser type, pages requested and the date and time of the request. We use it to keep the site secure and working, and delete it routinely.
- Preferences. If you switch between light and dark mode, that choice is stored in your browser’s local storage. It never leaves your device.
- Messages. If you email us, we use your email address only to reply.
Cookies and advertising
This site is free because it is supported by advertising. We use Google AdSense to show ads. Google and its partners use cookies to serve ads based on your prior visits to this and other websites. Google’s use of advertising cookies enables it and its partners to serve ads based on your visits to this site and/or other sites on the internet.
You can opt out of personalised advertising by visiting Google Ads Settings, or opt out of third-party vendors’ use of cookies for personalised advertising at aboutads.info. For more on how Google uses data, see How Google uses information from sites or apps that use its services.
Visitors in the European Economic Area, the UK and Switzerland will be asked for consent before personalised advertising cookies are used, through a Google-certified consent management platform.
Analytics
We may use Google Analytics to understand, in aggregate, which pages are useful and how visitors find the site. Google Analytics uses cookies and collects information such as pages visited and approximate location. You can opt out with the Google Analytics opt-out browser add-on.
Your rights
Depending on where you live, you may have the right to access, correct or delete personal data we hold about you, and to object to certain processing. Because we collect so little, most requests will concern server logs or emails. Contact us at support@grow-lytics.com.
Children
This site is intended for a general audience and is not directed at children under 13. We do not knowingly collect personal information from children.
Changes
We may update this policy from time to time. The date at the top shows when it was last changed. This policy applies to run.grow-lytics.com; our main site has its own privacy policy.
