Free coloring-scene trial terms

Updated September 7, 2026. This is a limited three-day free trial: one photo produces one coloring scene. No invite code, account or payment is required. It is not a subscription, finished coloring book or guarantee of likeness.

Choose only photos you have permission to use

Upload one clear, close-up portrait of one person, or one family photo with two to four people together, including two adults and two children. Make every face large and fully visible. Confirm the number shown; this is your declaration, not automatic identity recognition. We do not combine people from separate photos. You must have permission from everyone shown. For a child’s photo, their parent or legal guardian must authorize its use. Do not upload identification documents, intimate images or other sensitive material.

What happens to your photos

Selecting a photo initially opens it in your browser. Nothing is submitted until you confirm consent, complete human verification and press “Create my free coloring scene.” The browser prepares a smaller copy without the original filename or embedded photo metadata. That copy is sent over HTTPS to Vistuma’s server, held in a private queue, and retrieved by our local image computer for processing. We do not send these photos to paid image-generation APIs.

Private access, not a public gallery

When you submit, the service automatically creates a separate private browser session. The server sets a secure, HttpOnly session cookie to authorize your jobs and results. There is no shared public access code or public photo gallery. Return on the same browser and device; clearing cookies or using a private-browsing window that later closes can lose access to your results. Anyone using your browser session can access them. Older invitation sessions remain valid, and anyone holding an older invite code can still access that invite’s results. Do not share screenshots containing someone else’s photo without their permission.

No training or public reuse

Your uploaded photos and generated results are not used for model training, marketing, public examples or a stock library in this test. The local workflow uses existing model weights; it does not train a personal model from your photos.

Deletion and retention

Server input copies are removed when processing completes or fails. Working copies on the image computer are removed after each job. Results and job records are automatically removed within 24 hours of submission, normally within an additional one-minute cleanup interval. Use “Delete this test and its photos” to remove server copies sooner. If a job is already processing, cancellation is checked about every 15 seconds; its temporary local copies are removed when that job stops. If a computer is offline unexpectedly, cleanup may be delayed until it is available again. Downloads you save and copies on your own device are yours to manage.

Limits and experimental quality

Free submissions are limited per browser session and shared network. Each accepted submission produces one 768 × 768 pixel coloring scene. The server assigns a setting from eight adventures; settings rotate, but repeats are possible. People sharing Wi-Fi may encounter the shared network limit. Accepted submissions count toward these limits even if processing fails or a result is deleted. The trial has a maximum of 100 submissions overall, 50 per UTC day and ten waiting or processing jobs. Requests run one at a time. These controls identify browsers and networks, not verified individuals, and cannot perfectly prevent repeat visitors or bots. Starting a new browser session does not recover old results. The closing time is shown on the test page; reaching the cap may close access sooner. Completion time is not guaranteed. Facial features, anatomy, proportions or the number of people can look wrong; compare the result to the original. This is an experimental preview, not a finished print-ready book. There are no charges or automatic upgrades to a paid plan.

Human verification

Cloudflare Turnstile helps protect the free trial against automated submissions. Its widget processes browser and network signals under Cloudflare’s privacy terms. Vistuma verifies the challenge result on the server before accepting a generation job. Your selected photo is not sent to Turnstile. If verification is unavailable, new submissions stay blocked. A failed or expired challenge must be completed again.

Optional feedback

The feedback form collects ratings, selected problem categories and an optional comment. It does not attach your photos, results or image-job identifiers, and requires no name or email. Please do not include personal information in your comment. Answers are saved privately on Vistuma’s server for review and automatically removed after 30 days, normally within an additional one-minute cleanup interval. They are not used for model training or published as testimonials. If the service is offline, cleanup resumes when it restarts. Feedback uses a separate human-verification check. A keyed, daily network identifier is retained for up to two days to limit abuse; raw IP addresses and verification tokens are not stored in the feedback records. Hosting and security providers may still process normal connection information.

Website operation

The hosting and network providers may process normal request information such as IP addresses to deliver and protect the service. We use rate limits, a keyed network identifier for the test allocation limit, and essential session cookies, not advertising analytics. Session identifiers and minimal job state are used for private access and queue operation. No email, billing information or payment details are collected in this test.
