Privacy policy

Last updated 28 October 2026. This policy covers tlly.dev, its website, its members area, its MCP server and its API ("tlly", "we"), operated by tlly, a sole proprietorship, the controller of your personal data.

In short: we keep what we need to run your account and your dashboards, nothing more. We don't sell data, don't show ads and don't use tracking or advertising cookies. If you arrive from a campaign link, we store that source with your account when you sign up. Page-view counts, when the operator turns them on, are cookieless.

What we collect

How we use it

We don't use your data to train AI models, and we don't build advertising profiles.

Google user data

If you sign in with Google, tlly requests only the openid, email and profile scopes. We use your Google account ID to recognise you on later sign-ins and your verified email address as your account name, which also lets workspace owners invite you by email. We store those two values with your account, use them only to sign you in and run your account, and don't share them with anyone except as described under "Who we share it with". We don't access your Gmail, Drive, contacts or any other Google data.

tlly's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

Who we share it with

We don't sell or rent personal data. We share it only with service providers that help us run tlly, under their own data-protection terms: our hosting provider (servers and backups), our email provider (alert and confirmation emails), the AI model provider that answers the members-area chat (the messages you type there and the tool results it needs, such as series names and values; not your stored keys), and GitHub, Google or your organisation's identity provider (only to sign you in). We also disclose data if the law requires it, or to protect the safety and security of tlly and its users.

Dashboards are public to anyone with their link unless you make them private. Anything you put on a public dashboard can be seen by whoever has the link.

How long we keep it

When you ask us to delete your account we delete its data from the live service straight away; it disappears from backups as they expire.

Your rights

You can see, correct, export (CSV downloads on every dashboard and the audit log) or delete your data, and object to how we use it. Wherever you live, email us at hello [at] tlly [dot] dev and we'll respond within 30 days. If you're in the EU/EEA or the UK you can also complain to your local data-protection authority.

You can revoke tlly's access at any time from your GitHub settings or your Google account.

Cookies and page views

The session cookie (tlly_session) keeps you signed in. A second cookie (tlly_gh_state or tlly_google) exists only for about ten minutes while GitHub or Google sign-in completes, and holds a random check value, not a history of the pages you visited. We don't use tracking or advertising cookies, and we don't store a tracking identifier in your browser.

Campaign parameters travel in the link itself until you sign up. They are not a cookie.

Page-view counts are not collected on this server right now. If that changes, the counter is cookieless and is named here.

Security

All traffic is encrypted with HTTPS. API keys and session tokens are stored only as hashes, scheduled jobs can't reach private networks, and agents act only through credentials you can revoke. No system is perfectly secure; if we learn of a breach that affects your data we'll tell you without undue delay.

Children

tlly is a tool for work and isn't meant for anyone under 16. We don't knowingly collect data from children.

Changes

If we change this policy we'll update the date above, and for significant changes we'll tell account owners by email or in the members area before they take effect.
