What leaves your site
Two things can leave your site, and only two. Both are listed here in full.
When you generate metadata
Generation happens on our service, so the content being written about is sent to it. Per item, that is: the page title, its URL, its post type, the opening of its content (bounded — not the whole page), its public taxonomy terms, the metadata fields it currently holds, your site's name and tagline, and its language.
For an image, it is the image URL, its filename and dimensions, its caption and media-library title if you wrote them, and the title and type of the page it is attached to.
Not sent: your customers' data, your orders, any post meta belonging to other plugins, user accounts, or any content from a page that is not part of the run.
If you need to add a field or remove one, the
metaly_generation_context filter is the supported way to
do both.
The optional weekly report
Off unless you switch it on in Settings. Nothing prompts you to, and a site that never turns it on never sends anything.
What it contains, in full:
- which SEO plugin is active, and how many others compete with it;
- how many published items exist and how many are missing a title or description — per site, never per page;
- how many images exist, and how many have no alt text;
- your WordPress, PHP and Metaly versions, your site's locale, and whether WordPress considers the site production, staging or local;
- a one-way hash identifying this installation, salted with a random value generated on your own site and never sent. It lets one site's weekly reports be counted as one site; it cannot be turned back into an address.
Never sent: your site address, any email address, any user account, any post, title, description or other content, and your licence key.
Turning the setting off stops the weekly job immediately. Uninstalling deletes the salt, so a later reinstall is a different installation as far as we can tell.
Why we ask: which SEO plugins are really out there decides which of them gets fixed first, and the real size of the metadata gap is what plan sizes have to be priced against. Both are currently guesses.
Uninstalling
Deleting the plugin removes its tables, its options and its scheduled jobs, and releases the site slot on your licence. The metadata it wrote stays — it lives in your SEO plugin's fields, not in Metaly's. What you lose is the ability to undo those writes, because the record of what was there before goes with the plugin.
