Privacy, in plain English

SQUIRCLE / 方圆 · Last updated 29 August 2026

This notice explains what Squircle 方圆 uses to provide one room reading and keep the service safe.

Who is responsible?

The data controller is [legal name / EI — set before launch], trading as Squircle 方圆, [business address — set before launch]. Contact: [business email — set before launch] · [business phone — set before launch].

What we use

We process your room photo, selected room type and goal, payment/reference status, generated reading, and any feedback you choose to send. A one-way network-address hash is used briefly for upload rate limiting. If you ask us to email a result, the address is used for that delivery and is not added to a marketing list.

Why and for how long

We use this information to provide the paid service, prevent abuse, send a requested email, and meet accounting or legal obligations. Room photos are private and deleted immediately after a successful analysis; abandoned uploads are deleted after 24 hours. Reports and payment records are kept only as long as needed to provide the report and meet legal/accounting obligations.

Service providers

Mollie handles payments; OpenAI analyses the submitted image; Vercel hosts the app and private Blob storage; Neon stores reading state; Brevo sends an email only when requested. Providers may process data outside the EU under their published safeguards. The room photo is never attached to an email or share card.

Your choices

You may request access, correction, deletion, restriction, portability, or object to processing where applicable. Email [business email — set before launch]; we may need enough information to verify the request. You can also complain to the CNIL.

Links and privacy

No account is required. Your long, unguessable report link is the key to the result, so keep it private. A reopened or shared link contains structured findings but not the original room photo.
