Privacy notice

Last updated 19 October 2026

This notice says what personal data Quill & Bind keeps, why, and who processes it. The controller is David Gray Design Ltd, trading as Quill & Bind. Contact: support@mylne.com.

The data we keep

• Account: your email address, name and pen name, and the date you accepted the terms.
• Content: your books, stories, characters, pictures and exported files.
• Photos: a photo you upload to make a character. The photo is deleted when the character is approved, or when you delete the character. A written description of the appearance is kept with the character.
• Billing: your Stripe customer number, the state of your subscription and your credit history. Card details are held by Stripe. The studio does not see them.
• Assistants: the ChatGPT or Claude connections you approve, and when each was last used.
• Records: the jobs you start and their cost, for billing and to find faults.

Why we keep it

We use the data to provide the studio to you under the terms of use (contract), to take payment (contract), and to keep the accounts we must keep by law (legal obligation). We do not sell your data. We do not use it for advertising. We do not use your content to train AI models.

Who processes it

• Supabase stores the database and files, in London.
• Vercel runs the website, in London.
• OpenAI draws the pictures and writes the stories. It receives the prompt, and the character reference pictures and photo it needs for the picture. Under the OpenAI API terms, this data is not used to train models.
• Stripe takes payments.
• OpenAI (ChatGPT) or Anthropic (Claude), if you connect an assistant. The assistant sees what it reads or makes through the connection.

Some of these companies process data in the United States, under the UK International Data Transfer Addendum or the EU Standard Contractual Clauses.

How long we keep it

We keep your account and content until you delete the account. Then we delete it within 30 days, including from backups. We keep billing records for 6 years, as UK law requires.
