Privacy at CenterEye
The short version
CenterEye keeps what your AI saves to it. It doesn't keep your chats.
Your content is yours. CenterEye never sells it, never shares it, never uses it for ads or analytics, and never uses it to train AI. That includes the AI that writes your nightly synthesis: Anthropic's terms don't allow it to train on your data.
You can read your cards, checkpoints, tasks and hours on the web. You can download all of it, including what the web doesn't show, from your Profile. You can delete your account there too.
Who runs CenterEye
I'm Nikhil Singhal, and I build and run CenterEye through my company, OMSPARK LLC, in Redmond, Washington. If you have a question about your data, write to me at support@centereye.ai.
What CenterEye keeps, and why
Your account. Your email address and name. They let you sign in and let me reach you about your account. Your settings, such as your time zone and theme. Your password is stored only as a scrambled hash. I can't read it.
What your AI saves. Your areas, cards, checkpoints (the short notes your AI saves as work lands), tasks and their comments, logged hours and your synthesis. CenterEye keeps a history of changes to your cards. This is the record you and your AI apps work from.
Your connected apps. The name of each AI app you connect, and the sign-in tokens that let it reach your account. Tokens are stored as scrambled hashes too. When you connect an app, the site's admins get an email with your name and email address, the app, and the IP address and rough place it was approved from. They also get an email when an account is deleted or restored.
Your web sign-ins. Each sign-in on the web is kept with its IP address and browser, so your Profile can show the devices you're signed in on. A sign-in is deleted 12 months after it was last used.
Signing up. If you start signing up and never use the email link, the unfinished account is deleted after 8 days. When someone signs up, the site's admins get an email with the address, its IP address and roughly where the sign-up came from.
Text messages. CenterEye never sells or shares mobile numbers or text-message consent with anyone for marketing or promotion. Only admins can add a phone number, for their own alerts.
What CenterEye doesn't keep
Your chats. CenterEye sees only what an AI app sends when it saves something or asks for something, such as a checkpoint or your task list. It never receives the rest of the conversation.
The security log
Each time an app or your browser calls CenterEye, a short line is logged: which tool or page, when, which app, and the IP address and browser the call came from. For calls from an AI app, that IP address is usually the AI company's server, not yours. An IP address can show roughly where a request came from. A boot's line names the area booted. If a call fails, its line keeps the error, such as a misspelled area or card name. The log never holds the text of your cards, checkpoints or tasks.
I use it to keep accounts safe and to fix problems. For example, it shows a sign-in from somewhere new. It's kept for 12 months, then deleted.
When a limit refuses a request, the site's admins get an email with the IP address, roughly where it came from, and the account if one was signed in.
Your synthesis
On each night with new work in your account, CenterEye sends your new checkpoints to Claude, through Anthropic's API. It does the same when you or your AI ask for a fresh synthesis, and after each checkpoint save if you turn that on. With your new checkpoints go each area's short name and description, the previous synthesis, each area's number of open tasks and hours for the last 7 days, and the titles and due dates of open tasks that are overdue or due in the next 30 days. Claude writes the synthesis from them. Anthropic's terms don't allow it to train on that data.
You can turn the nightly run off on the Synthesis page.
Who else handles your data
CenterEye relies on a few services to run. Each one sees only what it needs to do its job.
- Hosting. CenterEye runs on a cloud server in San Francisco, in the United States.
- Backups. A copy of the database is saved each night to a cloud storage service.
- Bot check. The sign-up and forgot-password forms use Cloudflare Turnstile to keep out bots. Cloudflare sees your browser's signals for that check.
- Email. An email service sends your sign-up link, password resets and account notices.
- Synthesis. Anthropic, as described above.
- The AI apps you connect. Claude, ChatGPT, Grok, Gemini or any other app you connect reads from your account during your chats. Each app follows its own privacy policy.
If the law requires it, such as a valid court order, I may have to hand over data. Unless the law forbids it, I'll tell you first.
Cookies and analytics
CenterEye sets two cookies. The first, set on the first page you open, protects your account from forged requests. The second, set when you sign in, keeps you signed in. CenterEye uses no ad cookies.
The public pages of this website (home, docs, privacy and terms) use Google Analytics to count visits. Google Analytics works with cookies. You can read how Google uses that data at google.com/policies/privacy/partners, or block it with Google's opt-out add-on. Once you sign in, there's no analytics at all.
Download, delete and how long things last
Your data stays as long as your account is open.
You can download all of it from your Profile at any time. You get a zip file with your cards and checkpoints as files you can read, plus a complete copy of everything.
You can delete your account from your Profile too. It stops working at once. Any connected AI apps are cut off right away. Your account is held for 7 days in case you change your mind. Write to me in that time and I'll restore it. Then it's deleted for good.
Nightly backups are kept for 30 days. One backup a month is kept for 12 months. So deleted data can sit in a backup for up to a year after it's deleted for good. For an account, that year starts when the 7-day hold ends.
Keeping it safe
Every connection to CenterEye is encrypted. Passwords and connection tokens are stored only as hashes. Each account's data is kept apart from every other account's.
I do my best to keep your data safe. No service is perfectly secure. Please don't keep passwords, card numbers or medical records in CenterEye. If there's ever a breach that affects your data, I'll email you as soon as I know.
Your choices
In the app, you can correct your cards, tasks and hours, and download all of your data. You can delete checkpoints one by one and retire cards you no longer need. You can delete your whole account. If you want anything else, such as a question answered or something removed, write to support@centereye.ai. These choices are open to everyone, wherever you live.
Age
You need to be at least 13 to use CenterEye (16 in places where the law says so). If you're under 18, a parent or guardian should agree to the terms.
Changes
If this policy changes in a way that matters, I'll email you before the change takes effect. Every change is listed here with its date.
