At a glance
You can browse this website without giving us personal information. We do not use advertising trackers. We use PostHog and Google Analytics to count visits and see which pages and steps people use; neither records your screen or what you type. M3 is local-first: tests and runs you keep local are not stored by SineFrame. We store test results only when you explicitly choose to publish them to your SineFrame account.
Information we use
If you create an account, we handle your email address and account and organization details. If you choose to publish tests, runs, or reports to your account, we store that published content. Local tests and runs that you do not publish stay in your environment. We may also receive basic technical information, such as your IP address and browser type, when you visit the site or use the service.
On this site, the documentation, and the hosted app, we record page views and a few named actions, such as copying the agent skill prompt, creating an account, or creating an access token. These records carry a random visitor ID kept in a first-party cookie for sineframe.com, your browser type, and an approximate location derived from your IP address. Once you sign in, they are linked to your account ID and email address. They never include test content, tokens, or what you type. We send them to PostHog, our analytics provider, through our own domain.
This site and the documentation also load Google Analytics, which counts page views. It sets its own first-party cookies (named _ga) and sends Google the page address, your browser type, and an approximate location derived from your IP address. We have turned off Google's advertising features, so this data is not used to show you ads.
How we use it
We use this information to provide and secure M3, manage accounts, show content you chose to publish, send service-related emails, and respond to support requests. Sign-in may use essential browser storage to keep you signed in. We use analytics to understand how people find and use M3 and to improve it. We do not use your information for targeted advertising.
When we share information
We share information with service providers that help us host M3, manage sign-in, store account and published data, deliver emails, and measure how M3 is used. They receive only what is needed for those services. If you choose to sign in with a third-party account, that provider also handles information under its own privacy policy. We do not sell your personal information.
Your choices
You can browse the website without an account. You can request access to or deletion of your account information by emailing our contact address (shown when scripts load). We may retain limited information when needed for security, legal obligations, or routine backups.
Changes to this policy
We may update this policy as M3 changes. The date above shows when it was last updated.
