YOUR DATA
Privacy information
Jianwen Zhang operates Layout Studio. Questions can be sent through the contact page.
Work saved on your device
Prompt drafts, language preferences and manual poster projects are stored in browser storage. Images uploaded to the manual editor are read locally for composition. They are not sent to the image model by the upload action. Clearing browser data can remove those projects; export a project file to keep a separate copy.
Requests you choose to submit
Generating a prompt sends your written brief to the configured text-model provider through this server. Generating an image sends the prompt and image settings to fal. The generated result is retrieved from the provider. These services process requests under their own terms and privacy policies.
Accounts and purchase records
When connected, Supabase handles authentication and stores account identifiers, credit balances, credit transactions, order references and generation records. Image generation records store the submitted prompt, image size, task state and result link. PayPal processes hosted checkout and payment details. This application stores order and capture references, payment status and credit adjustments; it does not collect payment-card numbers.
Free prompt usage limits
To enforce daily limits, the server verifies signed-in account identities and counts requests against a daily account identifier. For guests, it uses a keyed, date-specific hash of the network address supplied by the hosting platform. Raw network addresses are not saved in this quota table. People on the same network share the guest allowance. Quota rows older than two days are removed when a later allowed request is processed. Submitted text-model attempts count even if the provider fails, so repeated failing requests cannot bypass the limit.
Cookies and technical records
Authentication uses cookies to keep a signed-in session. The hosting and service providers may keep technical logs to operate their services. This version does not add advertising trackers or an analytics SDK.
Retention and requests
Browser drafts remain until replaced or removed from that browser. Account, order and generation records currently remain in the database until the operator handles their removal; this version does not implement an automatic retention schedule. Payment records may be retained by the payment provider separately. Contact the operator for access or deletion requests before sending sensitive material.
