PlainSEO reads your Google Search Console data to tell you what is limiting your site in search. This page says what is collected, what it is used for, and how to have it deleted.
For any question about your data, or to have it deleted, write to mathis@plainseo.app.
What is collected
- From your Google account when you sign in: your name, email address and profile picture.
- From Google Search Console, once you connect it, with read-only access: the list of your properties, and for the property you pick, clicks, impressions and average position by page, by day and by search term, for up to 16 months.
- From Stripe, if you connect it with a read-only key: your successful payments since 28 months back (amount, currency, refunds, date, and which customer paid), read at each audit and counted into revenue and new customers by day. Single payments and customer details are not stored.
- From your site: the public pages that appear in your search data, fetched the way a visitor's browser would.
- What you tell the tool: what you sell, at what price, where your buyers come from, and your messages in the chat.
- If you subscribe: your subscription status. Card details go to Stripe and never reach this service.
What it is used for
- To produce your diagnosis, answer you in the chat, and run the weekly check.
- To send you the weekly report by email if you subscribe.
It is not sold, not used for advertising, and not used to train AI models.
Google user data
PlainSEO's use of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. Search Console data is used only to provide the features you see in the product. No person reads it, except with your permission, for security purposes, or to comply with the law.
Who processes it
- Anthropic: parts of your search data, your sales totals by month if you connect Stripe, page text, messages and the files you attach in the chat are sent to its AI models to label pages and write the diagnosis and chat replies. Attached files are stored there until you delete the conversation or your account. If you switch on web search in the chat, the searches are run by Anthropic.
- Stripe: payment, and, if you connect it, reading your own payments with the key you give.
- DataForSEO: when the chat looks up how often something is searched, the search phrases and the country are sent. Nothing that names you or your site is sent with them.
- Mailjet: sending email.
- The hosting provider that runs the application and its database.
How it is stored
Data is stored in a database operated for this service. The tokens that give access to your Search Console, and your Stripe key if you connect it, are stored encrypted.
Deleting your data
The Account page has a Delete account button. It cancels any subscription and deletes your site, its search data, the diagnosis, the case file and every conversation. You can also withdraw access at any time in your Google account, under third-party access.
