Lock-IN
Privacy Policy
Last updated: May 22, 2026
This policy describes how Lock-IN (“we”, “us”) handles information for the Lock-IN website, web app at lockinmusic.app/app, and the Lock-IN Focus Shield Chrome extension.
Lock-IN Focus Shield (Chrome extension)
The extension’s single purpose is optional distraction blocking during Lock-IN focus sessions. It only acts on websites that you choose in Lock-IN settings.
What we collect
The extension stores the following locally on your device using chrome.storage.local:
- Focus Shield on/off state and block mode (soft or hard)
- Your chosen block list (domain names only)
- Focus session end time and optional streak counter
- Timestamps when a blocked site was opened (block attempts)
- Temporary soft-block bypass timers (about 45 seconds per domain)
What we do not collect
- We do not sell or rent extension data to third parties
- We do not use extension data for advertising or analytics
- We do not include analytics SDKs in the extension
- We do not send your browsing history to our servers
- We do not read page text, images, passwords, or form content on blocked sites
How sync with Lock-IN works
When you use the Lock-IN web app on lockinmusic.app,
the app sends Focus Shield settings to the extension through a secure same-origin
postMessage channel. The extension content script runs only on Lock-IN app pages.
No account password or payment data passes through the extension.
Permissions and why they are used
- storage — save Focus Shield settings on your device
- tabs — detect navigation to user-selected blocked sites (soft mode) and open the Lock-IN app from the popup
- declarativeNetRequest — redirect blocked sites to our interstitial page in hard-block mode
- Host access — required because you may block any domain you add to your personal block list
Web history and activity
During an active focus session, the extension compares tab URLs against your block list. That may qualify as browsing-related activity under Chrome Web Store disclosures. This processing happens on your device only and is used solely to enforce your chosen blocking rules.
Data retention: Extension data stays on your device until you change settings, clear extension storage, or uninstall the extension.
Lock-IN web app and website
If you create an account, we store account information (such as email and profile settings) through our authentication provider (Supabase). Your song library and preferences may be stored in your account and in browser storage for faster loading. We use email delivery (Resend) for account verification messages.
We do not sell your personal information. We use data only to operate Lock-IN, improve the product, and communicate with you about your account when necessary.
Children
Lock-IN is not directed at children under 13. We do not knowingly collect personal information from children under 13.
Changes
We may update this policy from time to time. The “Last updated” date at the top will change when we do. Continued use of Lock-IN or the extension after changes means you accept the updated policy.
