How to Host a Privacy Policy for Free

What the URL has to do

Whatever you choose, the page must meet the same basic rules that Apple and Google check:

Public: it opens without a login, an invitation or a paywall.
Reachable everywhere: it isn't blocked in some countries or by bot protection.
A web page, not a file: Google Play doesn't accept PDFs.
Read-only: visitors can't edit it.
Clearly a privacy policy: titled "Privacy Policy" and naming you, the same developer or company as your store listing.
Stable: the address doesn't change, so the link in your app keeps working.

Option	Setup	Updating	Watch out for
GitHub Pages	A repository with an HTML or Markdown file, with Pages turned on	Commit and push	Free accounts need a public repository; you need basic Git
Google Sites	Build a page with your Google account and publish it	Edit and republish	Publish it to the public, not only to your organization
Google Docs	Use "Publish to the web"	Edits republish automatically	Share the published link, never the editing link; looks less professional
Notion	Publish the page to the web	Instant	Turn off editing and comments for visitors; check it loads in a private window
PDF file	Upload anywhere	Upload again	Not accepted by Google Play
Legiflare	Start from a template and publish	Edit online; the URL stays the same	Pages show the Legiflare header and footer

GitHub Pages is a solid choice if you already use GitHub:

Create a repository, for example privacy-policy, and add an index.html or index.md with your policy.
In the repository settings, open Pages and publish from your main branch.
Your policy appears at https://your-username.github.io/privacy-policy/.

You still need the policy text itself. The privacy policy template works well as a starting point.

Create a free account and start from the privacy policy template, or describe your app to get a first draft.
Edit the sections so they match what your app really collects, and publish.
Copy the link and paste it into App Store Connect, the Play Console and your app's settings screen.

When something changes, edit the text online. The link stays the same, so you don't have to update your store listings.

Open it in a private browser window to confirm it doesn't need a login.
Open it on your phone, on mobile data, to confirm it loads and is readable.
Check the title says "Privacy Policy" and the developer name matches your store listing.
Check it covers the platform rules for iOS and Android.

No. Apple and Google accept any public URL that meets their rules. Your own domain looks more professional, but it isn't required.

Only through "Publish to the web", which gives a read-only page. Never paste a sharing link that lets people edit or request access.

Update the link in both stores and inside your app, and keep the old page online until all of them point to the new one.

Yes. Templates, editing and hosting are free, with no limit on the number of documents.
