Privacy
This page explains what personal data the Datarithms website collects today and what we do with it. Datarithms is operated by Pyramid Works LLC, a company in the United States ("we", "us").
What we collect
- Early-access requests. When you fill in the early-access form we store your work email, your company name, the monthly ad spend range you chose, and whether you are a company or an agency.
- Accounts. During early access, accounts are created by invitation only. For each account we store the email address, a one-way hash of the password (never the password itself), the account role, when the account was created and when it last signed in.
- Security records. To limit abuse we record sign-in attempts (email, time, success or failure) and form submissions. We store a one-way, keyed hash of your IP address with these records, never the IP address itself.
- Server logs. Our hosting keeps basic technical logs (such as time, requested page, response status and IP address) to run and secure the service.
What we do not do
The site uses no advertising cookies, no analytics trackers and no third-party pixels. We do not sell personal data and do not share it for advertising.
Cookies
We use one strictly necessary cookie: a session cookie that keeps you signed in after you sign in. It is set only when you sign in. The sign-in form also sets two short-lived helper cookies: one protects the form against forged requests and one remembers the page to return to. Visitors who do not sign in get no session cookie.
Why we use it
We use early-access details to reply to you and decide who to onboard. We use account data to let you sign in and to keep accounts secure. We do not use your data for automated decisions about you.
The product, later
When the Datarithms product is available to you, it will read data from your ad accounts and your payment or sales tools only after you authorise each connection. Access will be read-only. That data is used only to produce your reports and plans, is never sold, and is deleted on your request. We will update this page before any of that starts.
Who processes it
Data is stored on servers we rent from our hosting provider, which processes it on our behalf. We do not use other third parties for the data described above.
How long we keep it
Early-access requests are kept until early access ends or you ask us to delete them. Account data is kept while the account exists. Security records and server logs are kept only as long as needed for security and troubleshooting.
Your choices
You can ask us to show you, correct or delete the personal data we hold about you. Write to privacy@datarithms.io. We reply within 30 days. Depending on where you live, you may also have the right to complain to your local data protection authority.
Changes
If we change this page, we update the date at the top. Material changes will be announced on this site.
