Privacy Policy

1. What we collect

• Your account: your email address, a protected form of your password, and, if you sign in with Google or Microsoft, the name, email address and account identifier they send us.
• What you make: every question you type, any picture or file you attach to it (a picture is kept as a smaller copy, a document as its words), each sketch and each earlier version of it, its spoken explanation as audio, a small picture of it, and the language, kind and look you chose.
• Your plan and use: which plan you are on, how many sketches you have made, and a record of each piece of work done for you and what it cost us.
• Payment: when you buy a plan, Stripe collects your card and billing details. We receive a customer reference, your plan and its dates and status, never your full card number.
• What you tell us: a rating or note you leave on a sketch, and any message you send us.
• Technical records: your internet address, browser type and the time of each request, kept by our hosting company and by us to run the service, stop abuse and find faults.

2. What we keep in your browser

Sketchwise sets no advertising or tracking cookies and runs no analytics from other companies. It keeps a few items in your browser's own storage so the site works: the key that keeps you signed in, your basic account details, the language you chose, and whether you prefer a light or dark screen. Clearing your browser's storage for the site removes them and signs you out.

The payment page is Stripe's own and sets the cookies Stripe needs to take a payment safely and prevent fraud.

3. Why we use it

• To do what you asked: make, keep, play, share and export your sketches, and run your account and plan. This is needed for our agreement with you.
• To take payment, send receipts and the emails an account needs (confirming your address, resetting a password, notices about your plan).
• To keep the service safe and working: preventing abuse, finding faults, and measuring cost and quality. This is our legitimate interest in running a reliable service.
• To meet legal duties, such as keeping records of payments.

We do not use your questions, what you attach to them, or your sketches to train models, and we do not send marketing email unless you have asked for it.

4. Who else handles it

We use other companies to run the service. Each receives only what its part needs, under terms that limit what it may do with it:

• Anthropic: receives your question, any picture or file words you attach to it, and your sketch when you ask for a change or a check, to write and draw the sketch.
• Google and OpenAI: one of them receives the sentences of the explanation, to turn them into speech.
• Cloudflare: hosts the site, stores accounts, sketches, what you attach and audio, and sends our email.
• Stripe: takes payments and holds your card and billing details under its own privacy policy.
• Google or Microsoft: only if you choose to sign in with them.

Your name and email address are not sent to the companies that draw and speak. We may also disclose information when the law requires it, or to a buyer of the business, who would be bound by this policy.

5. Sharing a sketch

A sketch is private to your account. If you make a link for it, anyone with the link can watch that sketch and hear its explanation, on our site or placed in another page. The link shows the sketch and its title, never your name, your email or your other sketches. We ask search engines not to list shared links. You can turn a link off at any time, and it stops working at once.

6. How long we keep it

We keep your account and sketches for as long as the account is open. A sketch you delete leaves your account at once and can no longer be opened or shared. Its stored files are erased when you ask us to, or when your account is deleted. When you ask us to delete your account we erase it and what it holds within 30 days, except records we must keep by law (such as payment records) and backups, which run out on their own schedule.

7. Where it is kept and how it is protected

Information is stored and processed on the systems of the companies above, which may be in a country other than yours, including the United States. Where the law requires it, we rely on recognised safeguards, such as standard contractual clauses, for those transfers.

Information is encrypted on its way between you and us and where it is stored, passwords are never kept in readable form, and access is limited to what running the service needs. No system is perfectly secure. If a breach puts your information at risk we will tell you and the authorities as the law requires.

8. Your choices and rights

Depending on where you live, you have the right to see the information we hold about you, to have it corrected or deleted, to receive a copy, to object to or restrict some uses, and to withdraw a consent you gave. To use any of these, write to contact@kronosense.com from the address you sign in with. We answer within 30 days and never charge for it or treat you differently for asking.

If you are in the European Economic Area, the United Kingdom or another place with a data protection authority, you may also complain to that authority. We do not sell personal information or share it for advertising.

9. Children

Sketchwise is not for children under 13, and we do not knowingly collect their information. If you believe a child under 13 has made an account, write to contact@kronosense.com and we will delete it. A school or teacher who wants to use Sketchwise with younger pupils should write to us first.

10. Changes to this policy

When we change this policy we change the date at the top. When a change matters, we tell you by email or in the studio before it takes effect.
