The short version
- No accounts. You never sign up, so we have no profile, password or email address for you.
- Your files stay on your device in tools marked 🔒 Runs in your browser. PDFs, photos, videos and documents are processed by your own browser and are never uploaded to us.
- No advertising cookies and no tracking across sites. We count visits without cookies.
- Some tools need an online service to work (AI steps, video rooms, screen sharing). Each one is labelled on the homepage and on the tool page, and only what that step needs is sent.
Who runs this site
MigaBuilder (migabuilder.com) is an independent, open-source project. For anything about your privacy, write to contact@migabuilder.com.
What is stored in your browser
Tools save things like your recent and favourite tools, your language, drafts, settings and the work you choose to keep (“My work”) in your browser’s own storage (localStorage and IndexedDB). This stays on your device; we cannot see it. You can delete it at any time by clearing this site’s data in your browser settings. If you paste your own AI key into a tool, it is kept only in memory unless you tick “Remember”, in which case it is stored in this browser only.
What is sent online, and to whom
| When | What is sent | Who receives it |
|---|---|---|
| Every page | A cookieless page-view count (page address, browser type, rough country, from the request itself). No cookies or identifiers. | Cloudflare Web Analytics |
| Opening a tool | Only the page name (for example “qr-forge.html”), to count how often each tool is used. No cookies, identifiers or content. | MigaBuilder’s visit counter (a Cloudflare Worker) |
| Loading any page | Your IP address and browser details, as with any website, to deliver the page, fonts, code libraries and videos. | GitHub Pages (hosting), Cloudflare, Google Fonts, cdnjs and jsDelivr |
| AI steps (🌐 tools) | The text, and in some tools the pictures, you ask the AI to work on. | Google Gemini, through MigaBuilder’s proxy, or OpenAI / Anthropic / Google directly if you choose your own key |
| Meet Forge | Your video, audio and chat in the room. | Jitsi Meet (meet.jit.si). MigaBuilder does not record calls. |
| Screen Share Forge | A one-time connection setup message. The screen, audio and chat then go directly between the two browsers. | MigaBuilder’s connection relay (a Cloudflare Worker) |
| Post Forge | The post you write, sent to the networks you pick, using the login or webhook you enter. | Discord, Bluesky and/or Mastodon |
| Species Atlas, Geography Forge | Your searches, to fetch photos, maps and facts. | iNaturalist, OpenStreetMap, Wikipedia and Wikidata |
| Feedback page | The message you write. It is published as a public GitHub issue, so don’t include personal details. | GitHub, through MigaBuilder’s feedback relay |
| Shop | Your payment and email details, entered on the checkout page. | Stripe. We receive your email and what you bought so we can deliver the download; we never see your card details. |
AI services
When you use the free Gemini option, your request goes through MigaBuilder’s proxy to Google’s Gemini API. The proxy does not store your text. Google processes it under its own terms, and on the free tier Google may use it to improve its services, so don’t send anything private or confidential to an AI step. If you choose your own OpenAI, Anthropic or Gemini key, your browser talks to that company directly and their privacy policy applies.
Children
MigaBuilder has no accounts and does not knowingly collect personal information from anyone, including children. Teachers and parents should supervise the tools that use AI or go online.
Your rights
Because we do not keep accounts or profiles, there is usually nothing about you for us to show, correct or delete. If you think we hold something (for example a shop order or a feedback message), write to contact@migabuilder.com and we will help. If you are in the EU, UK or another place with data-protection law, you can also complain to your local data-protection authority.
Changes
If what the site sends changes, we update this page and the date at the top. The site is open source, so you can check exactly what each page does on GitHub.
