Stash has a live privacy policy at https://stash.illo.fyi/privacy (we just updated it to cover short-link KV storage and PostHog analytics). AMO requires a privacy policy URL for any listed add-on that interacts with user data, and even though the extension itself collects nothing, tab URLs/titles count as user data, so providing the policy is expected.
