Privacy Policy

Free tools, no data leaves your browser

All 19 utilities (JSON, Base64, JWT, Hash, Regex, Timestamp, Color, UUID, Lorem, Markdown, Diff, Cron, Password, QR Code, YAML, Gradient, HTML Entities, JSON→TS, URL) run entirely client-side in your browser. Whatever you paste (JWTs, JSON payloads, passwords, URLs) stays on your device. We do not collect, transmit, store, or analyse the content you put into the tools.

When you create an API key (Pro tier)

To use the DevTools Hub API for high-volume automation, you create an account and an HMAC-signed API key. We collect:

• Email address: for account identification, billing receipts, and security alerts
• API key metadata: key prefix, creation date, last-used timestamp, rate-limit usage (we never store the full key plaintext after creation, only a hash for verification)
• API request metadata: timestamps, endpoint called, response status, originating IP (for rate-limiting and abuse detection; not the request body)

Payments (Pro subscription)

DevTools Hub Pro is $9/month, billed via Stripe. Stripe collects your name, email, billing address, and payment-card details to process the subscription. Stripe shares with us: your email, the subscription status, billing amount, and renewal/cancellation events. We do not see or store your card details. Stripe's privacy policy: stripe.com/privacy.

Hosting logs

Vercel (our hosting provider) records standard request metadata (IP address, user agent, request path, response status, timestamp) for security and operational reasons. Logs are retained per Vercel's defaults.

What we don't do

• No Google Analytics, no Google Ads, no Facebook Pixel, no behavioural tracking
• No cookies for advertising or third-party tracking
• No selling or sharing of personal information for cross-context behavioural advertising
• No reading or storing of tool inputs (the content you paste in)

Who we share data with

Only service providers that help us run DevTools Hub:

• Stripe, Inc.: Pro subscription payment processing
• Vercel Inc.: hosting and request logs
• Google LLC: Google Workspace mailbox (admin@ten30studio.com) for support email

International transfers

DevTools Hub is operated from the United States, and our service providers (Stripe, Vercel, Google) process data in the US. If you are in the UK or EU, your data may be transferred to and processed in the US under the recipient providers' Standard Contractual Clauses or Data Privacy Framework participation.

Retention

• API request logs: 90 days, then deleted
• Subscription records: at least 7 years (tax / accounting)
• Hosting logs: per Vercel's defaults

Your rights (UK / EU GDPR)

If you are in the UK or EU, you have rights of access, rectification, erasure, restriction, portability, objection, and the right to lodge a complaint with your supervisory authority (UK: Information Commissioner's Office). Lawful basis: contract (Pro subscription), legitimate interest (running the site, security), legal obligation (tax records). To exercise any right, email admin@ten30studio.com. We respond within 30 days.

Your rights (California, CCPA / CPRA)

California residents have the right to know, delete, correct, and opt-out of sale or sharing. We do not sell or share personal information for cross-context behavioural advertising. Categories of personal information collected in the past 12 months: identifiers (email, IP), commercial information (subscription records), internet activity (API request metadata). To exercise a California right, email admin@ten30studio.com.

Security

HTTPS in transit. API keys are stored as cryptographic hashes (not plaintext). Account passwords (if applicable) are stored using bcrypt or equivalent. No method of internet transmission or storage is completely secure.

Children

DevTools Hub is not directed to children under 16, and we do not knowingly collect their information.
