Applies to Sylphx-operated surfaces only. Applications that customers build on Sylphx manage their own consent banners.
1. What Are Cookies
Cookies, local storage and the surfaces this policy covers.
Cookies are small text files stored on your device. We also use local storage and similar technologies for the same purposes described below.
- Cookies
- Small text files stored on your device by the surfaces you visit.
- Local storage
- Device-side storage used for the same purposes as cookies in this policy.
- Sylphx-operated surfaces
- sylphx.com and the Console — the surfaces this policy covers. Customer applications that embed Sylphx Consent BaaS manage their own banners.
- Consent preference center
- Where non-essential choices are recorded, on the surfaces where it is shown.
2. How We Use Cookies
Three jobs: keep you signed in, remember preferences, measure reliability.
We use cookies to:
- Keep you signed in and protect sessions
- Remember UI preferences (theme, locale, consent choices)
- Measure aggregate product usage so we can improve reliability
Sylphx Limited is responsible for the cookies set on Sylphx-operated surfaces. We do not use cookies to sell personal data. See the Privacy Policy for the full processing story.
3. Cookie Categories
Essential, functional, analytics — what each covers and whether consent gates it.
| Category | What it covers | Consent | If it is blocked |
|---|---|---|---|
| Essential | Authentication, CSRF, load-balancing, and security controls | Required for the service to function | Blocking essential cookies may prevent sign-in and Console use |
| Functional | Preference memory (e.g. theme) | Can be disabled | Some UX features may reset |
| Analytics | Aggregate product analytics | Only set when consent allows (Consent BaaS preference center) | No analytics cookies are set when consent is not given |
What this policy does not list
It publishes categories, not per-cookie names or individual lifetimes. Your browser's developer tools show exactly which cookies a given session sets and for how long.
4. Managing Preferences
Two controls: your browser, and the consent preference center where it is shown.
You can manage non-essential cookies through your browser settings or, where shown, the Sylphx consent preference center. Blocking essential cookies may prevent sign-in and Console use.
Customer applications that embed Sylphx Consent BaaS manage their own banners; this policy covers Sylphx-operated surfaces only.
5. Third-Party Cookies
Two named providers may set cookies on our surfaces: Stripe and Cloudflare.
Payment flows may set cookies controlled by Stripe. Edge protection is provided by Cloudflare. Those providers process data under their own policies and our sub-processors list.
| Provider | Where its cookies can appear | Governing terms |
|---|---|---|
| Stripe | Payment flows | Stripe’s own policies, plus the sub-processor contract |
| Cloudflare | Edge protection for Sylphx-operated surfaces | Cloudflare’s own policies, plus the sub-processor contract |
Both are listed with their region and contract in Sub-processors.
6. Updates
Changes are posted here with a new date.
We may update this policy, for example as our surfaces or providers change. We will post the new version here and update the date above. Before we set a new cookie that the law requires consent for, we will ask for it.
