What data does SideFetch collect?

SideFetch doesn't collect any data. Your API requests go directly from your browser to the target API. All data is stored locally in Chrome using chrome.storage. The only external call is for AI error explanations.

Frequently asked questions

Is SideFetch really free?

Yes. The Free plan is free forever with no trial period. You can send unlimited requests using all HTTP methods, all 12 auth types, cURL paste, and the JSON tree viewer. Free includes 10 history items, 1 collection, and 3 AI explanations per day.

How does the Pro plan work?

Pro costs $5.99/month or $29/year (save 60%). After checkout via Lemon Squeezy, your license key activates in the extension. You get unlimited history, collections, AI explanations, import/export, and environment variables.

What data do you collect?

We don't collect any data. Your API requests go directly from your browser to the target API. All data (history, collections, settings) is stored locally in Chrome using chrome.storage. The only external call is to Groq's API for AI error explanations — and that only sends the error context, not your full request.

Does it work on all websites?

SideFetch opens in Chrome's Side Panel, which is available on any website. You can test APIs while reading documentation, browsing your app, or working in any web tool.

Can I cancel anytime?

Absolutely. Cancel your Pro subscription anytime from your Lemon Squeezy customer portal. You'll keep Pro features until the end of your billing period. We also offer a 7-day money-back guarantee.

How do I get a refund?

Email us at support@sidefetch.com within 7 days of purchase and we'll process a full refund — no questions asked.
