Terms of service
Last updated September 27, 2026
The service
reachlag analyses public YouTube channel data and shows you what happened: which videos over- and under-performed, the ratio of subscribers to typical views, dead links in descriptions, and changes in upload rhythm. It is information, not advice. We make no promise about future views, subscribers or income.
Your account
Keep your sign-in details to yourself. You are responsible for activity under your account. Fair-use limits apply to how many reports an account can generate; automated or abusive use may be blocked.
Data sources
Data comes from the YouTube Data API. By using reachlag you agree to be bound by the YouTube Terms of Service, and Google’s handling of that data is described in the Google Privacy Policy. Numbers in a report are a snapshot taken when the report was generated; ratios and scores are calculated by reachlag, not YouTube.
No warranty
The service is provided as is. We work to keep reports accurate and to say clearly when something could not be verified, but we cannot guarantee completeness, and we are not liable for decisions made from a report.
Changes
We may update these terms; the date above shows the current version.
