privacy policy

dsl·ai is built to do one thing — make an llm reliably produce your domain-specific language — without watching you do it. the playground runs entirely in your browser.

last updated: 10 june 2026

the short version

dsl·ai’s playground processes everything locally in your browser. it has no accounts, no analytics, and no server that sees your grammars or input. it does not collect, store, sell, or share any personal data.

who we are

dsl·ai is built by ogbuilds, a uk-based studio, as a build-in-public product. this policy is written to be honest about how the product works today, under uk data-protection law (uk gdpr).

what we collect

nothing personal. dsl·ai does not collect names, emails, or identifiers. there are no accounts, and there is no analytics or tracking code in the app.

the grammars you paste, the snippets you validate, and the output the playground generates never leave your browser. there is no server-side llm call and no database — the constrained-generation and validation engine is plain code that runs on your own machine.

how the playground works

when you paste a grammar and hit generate or validate, dsl·ai compiles your grammar into a decoding constraint and a deterministic parser, then runs both directly in your browser. no grammar, snippet, or generated line is uploaded, stored, or logged anywhere.

this happens only when you ask for it — nothing runs in the background, and there is no telemetry reporting on what you do.

cookies & local storage

dsl·ai sets no cookies and uses no advertising or tracking technologies. anything you type lives only in the page while it is open and is gone when you close or reload the tab.

third parties

the playground sends nothing to third parties. dsl·ai contains no advertising, no trackers, and no third-party analytics. the site is hosted on vercel, which (like any web host) processes standard request metadata such as ip addresses to serve and protect the pages — vercel does not receive your grammars or input.

legal basis (uk gdpr)

because dsl·ai does not collect or store personal data, there is no personal-data processing for us to rely on a legal basis for. any standard request metadata handled by our host (vercel) is processed on the basis of our legitimate interest in delivering and securing the site.

your rights

under uk gdpr you have rights to access, correct, delete, and export personal data we hold about you, and to object to or restrict its processing. since dsl·ai holds no accounts and no personal data, there is nothing for us to retrieve or erase — but if you believe we hold anything about you, reach out via the studio link below and we’ll respond.

international transfers

our host, vercel, is a us-based company and may process the standard request metadata described above outside the uk/eea, under the appropriate safeguards (such as the uk addendum to the eu standard contractual clauses).

children

dsl·ai is a developer tool and is not directed at children under 13. we do not knowingly collect data from anyone, including children.

security

the site is served over https, so traffic between your browser and our host is encrypted in transit. because processing happens locally and we store no personal data, there is no stored user data for us to secure.

future paid features

the roadmap includes optional paid tiers — a hosted api, a ci validation check, retrieval over your docs, and optional fine-tuning of small self-hosted models. those features would send the specific grammars or input you choose to a server in order to work, and would require accounts and billing. none of that exists today; this policy will be updated to describe it before any such feature launches.

changes

if this policy changes, we’ll update the date above and, for material changes, note it on this page.
