domain.

+          <h1>Photo metadata privacy checklist</h1>
+          <p class="lead">Run through this list before you post, sell or send a photo. It takes under a minute and covers the details people most often leak by accident.</p>

+<h2>Before you share</h2>
+<ol>
+<li><strong>Check for location.</strong> If the photo was taken at home, work or school, assume it has GPS coordinates until you have looked.</li>
+<li><strong>Check the device and time.</strong> Camera model, serial numbers and capture time can link photos to one person.</li>
+<li><strong>Check creator and software fields.</strong> They can hold your name, your editing apps or an account.</li>
+<li><strong>Check for content credentials.</strong> Some apps and AI tools add a signed edit history. See <a href="/guides/what-is-c2pa/">what C2PA is</a>.</li>
+<li><strong>Clean the file, then check again.</strong> Scan the cleaned copy to confirm nothing survived.</li>
+</ol>
+<h2>When it matters most</h2>
+<ul>
+<li><strong>Selling items online:</strong> photos taken in your home can expose your address to buyers.</li>
+<li><strong>Posting about children or family:</strong> remove location from photos taken at home or school.</li>
+<li><strong>Journalism and activism:</strong> metadata can identify a source, a device or a place.</li>
+<li><strong>Dating and meetups:</strong> a precise location should never travel with a photo to a stranger.</li>
+<li><strong>Sending original files:</strong> email, cloud links and document-style attachments keep everything.</li>
+</ul>
+<h2>Make it a habit</h2>
+<p>Switch off location tags in your camera app, then clean any photo you share as a file. <a href="/#tool">Untrace</a> handles up to 50 photos at once in your browser, so there is nothing to upload and nothing to install.</p>
+<div class="callout"><p><strong>Remember what metadata cannot hide.</strong> The picture itself can still reveal a place. Check backgrounds, signs and reflections as well.</p></div>
+<div class="cta"><p><strong>See what your own photo is hiding.</strong> Untrace lists every metadata block, then removes it, all inside your browser.</p><a class="btn btn-primary" href="/#tool">Scan a photo</a></div>
+          <h2>Common questions</h2>
+          <h3>How long does the checklist take?</h3><p>Under a minute for a single photo. Batch cleaning makes it quick for an album too.</p><h3>Do I need to clean every photo I share?</h3><p>Only the ones that leave your control as files. Photos you only view privately do not need it, but cleaning before you send is a safe default.</p>
