Privacy policy
Last updated 28 October 2026
Who we are
Luminka is a service that lets you create and edit images in Claude. It is run by Squie Limited, a company registered in England and Wales (company number 07722811), registered office 80 Browning Road, Enfield, EN2 0EJ. Squie Limited is the data controller for the personal information described here.
Questions about privacy, or requests about your data: support@squie.com.
Luminka is independent and is not affiliated with Anthropic (the maker of Claude) or OpenAI.
What we collect and why
| Information | Why we use it | Legal basis |
|---|---|---|
| Your email address | To create your account, send sign-in codes, and contact you about your account or purchases. | Contract |
| Your prompts and images: the descriptions you ask for, images you edit, and the images we make | To make the images you ask for, show them in Claude, and keep a 30-day history on your account page. Also to help you when you contact support, and to investigate abuse. | Contract; legitimate interests |
| Credits and purchases: balance, a log of credit changes, packs bought and refunds | To run the credit system, prevent abuse, and keep accounting records. | Contract; legal obligation |
| Your OpenAI API key, only if you add one | To make images with your own OpenAI account instead of credits. | Contract |
| Technical data: IP address, browser, request logs, sign-in events | To keep the service secure, stop bots and abuse, and fix problems. | Legitimate interests |
We do not use your information for advertising, we do not sell it, and we do not use your prompts or images to train any AI model.
Inside Squie, only the people who run Luminka can see account information, through a private admin page that needs a sign-in. It shows your email, credits, purchases, how many images you've made and your most recent prompts. We look at it to run the service: to answer support requests, check payments, investigate abuse, and understand usage and costs. We don't browse people's prompts or images for any other reason.
Your OpenAI key
If you add your own OpenAI API key, it is checked with OpenAI and stored encrypted. It is only ever used by our server to make your images, is never shown to you or anyone else again (we display only its last four characters), and is permanently deleted when you remove it or delete your account. Images made with your key are billed to your OpenAI account under OpenAI's terms.
Payments
Payments are handled by Stripe. Your card details go directly to Stripe and never reach Luminka. We receive a record of the purchase (amount, currency, pack and status), and Stripe keeps its own records as required by law.
Who we share it with
We use these service providers ("processors") to run Luminka. They may only use your information to provide their service to us:
| Provider | What for | Where |
|---|---|---|
| OpenAI | Generating and editing images from your prompts | United States |
| Supabase | Accounts, sign-in, database, encrypted key storage | United Kingdom (London) |
| Vercel | Hosting the website and connector; storing image files; counting page visits and measuring how fast pages load (Web Analytics and Speed Insights, which use no cookies and don't identify you) | United States and global network |
| Stripe | Payments and VAT calculation | United Kingdom, EU and United States |
| Resend | Sending sign-in emails | EU (Ireland) |
| Cloudflare | Bot protection on sign-in (Turnstile), and serving the website's animation library (cdnjs; receives your IP address) | Global network |
| Google Fonts | Serving the website's fonts (receives your IP address) | Global network |
Where information is transferred outside the UK, it is protected by the UK's adequacy regulations or the providers' standard contractual safeguards (such as the UK International Data Transfer Addendum).
Claude: when you use Luminka in Claude, your conversation, including your requests and the images we return, is also handled by Anthropic under Anthropic's own privacy policy.
We may also disclose information if required by law, or to protect the rights and safety of our users or the public.
How long we keep it
- Stored image files are deleted automatically after 30 days. After that, download links stop working.
- Your account, history, credits and saved key are kept until you delete your account.
- Purchase records: when you delete your account we delete ours. Stripe keeps payment records for as long as the law requires, typically six years.
- Technical logs are kept for a short period, normally up to 30 days.
Cookies and local storage
We don't use advertising or analytics cookies. Your browser stores your sign-in session in local storage so you stay signed in. This is strictly necessary for the service, so we don't ask for consent. Cloudflare's bot check may set a strictly necessary security cookie.
Your rights
Under UK data protection law you can ask to access, correct, delete or export your information, and to object to or restrict how we use it. You can delete your account and everything stored for it at any time from your account page. For anything else, email support@squie.com. We'll reply within one month.
If you're unhappy with how we handle your information, you can complain to the Information Commissioner's Office (ico.org.uk), though we'd appreciate the chance to sort it out first.
Children
Luminka is not intended for anyone under 18, and we don't knowingly collect information from children.
Changes
If we make significant changes to this policy, we'll update the date at the top and, where appropriate, let you know by email.
