Privacy, in plain language.
DLL Studio lets visitors meet fictional characters, watch short clips, and play without creating an account. This page describes the current website.
Games and videos
Optional memberships add parent accounts, paid subscriptions, and private video requests. Clerk handles sign-in and Stripe handles billing. DLL stores membership status, credit usage, optional birthday month/day and timezone, parent scripts, review status, publishing permission, votes, badges, and gift box allocations. Parent scripts are checked through OpenAI and approved scenes are generated through FAL. See parent controls and membership data for details. Public play remains available without an account.
Games run in your browser. Scores and progress are not uploaded or stored by the app. Character images and videos are served as website files. We use Vercel Web Analytics to measure page visits and Vercel Speed Insights to measure website performance. We do not send game scores, character conversations, or video scripts to these analytics tools.
YouTube episodes
The Watch episodes page embeds DLL Studio’s YouTube uploads using YouTube’s privacy-enhanced player. Loading the player connects your browser to YouTube and Google, which process connection information and may use storage under their own policies. YouTube may show non-personalized ads. Available captions and audio languages are provided by YouTube. See the Google Privacy Policy.
Character conversations
Chat accepts only preset question buttons. The app sends the character ID and selected topic to our server; it does not accept typed messages, photographs, audio, personal profiles, or chat history. AI replies are produced through OpenAI and checked by its moderation service. We request that generated responses not be stored as Responses API conversation records; provider security and abuse-monitoring practices still apply.
We do not send a visitor’s name, IP address, or other identifying information to OpenAI as part of the generation request. Displayed conversations exist only in the current page’s memory. Our server may temporarily cache a generated answer for a character and topic; that cache is not linked to an individual child.
Basic hosting information
Vercel, our hosting provider, processes connection information such as IP addresses and request metadata to deliver and protect the website. The chat endpoint uses a temporary hash of the connection address to limit requests. These limits reset, and the app does not create a persistent visitor profile. Infrastructure providers may retain operational or security logs under their own policies.
External services
Fal was used to create the character intro videos before publication. Playing the finished videos does not send chat messages or gameplay to Fal. Google Drive and GitHub are production tools and are not connected to the children’s play experience.
