Terms of Service Version History

What is a terms of service version history?

A terms of service version history is a record of every past version of a vendor's terms, with the date each one applied. It lets you see what the terms said on a given day, and what changed between versions.

The same idea applies to any legal page: the privacy policy, the data processing agreement, the subprocessor list or the pricing terms.

Some vendors publish their own history. The GitHub Terms of Service say you can view all changes to them in GitHub's public Site Policy repository. Atlassian keeps an archive of past agreements, such as its April 2014 Customer Agreement. Many vendors keep no public archive at all and simply replace the page.

Why it matters to you

The version that applied on the day something happened usually decides the outcome. If you dispute a bill, report a data incident or question how your data was used, you need the terms from that date, not today's version.

Proof of what you accepted also matters when a vendor's change is challenged. In Douglas v. U.S. District Court (9th Cir. 2007), the question was whether a customer was bound by revised terms he was never told about. Questions like that turn on which version existed when, and what notice was given. Law firm Morgan Lewis advises vendors to track which version of the terms applies to which user.

What to check

• Whether the vendor publishes past versions or a change log.
• Whether each version shows an effective date, not only a "last updated" date.
• Save a dated copy of each key vendor's terms when you sign up and renew, with any change notice emails.
• For a negotiated contract, keep the signed version and any order forms that point to online terms.

How to see old versions of terms

If the vendor keeps no archive, you have three main options.

1. Check the vendor's own site for an archive or change log. Search the legal page for "previous versions" or "archive."
2. Use the Internet Archive's Wayback Machine at web.archive.org. Paste the URL of the terms page and pick a date from the calendar of saved copies.
3. Look in your own records: saved PDFs, contract files and old notice emails.

The Wayback Machine has limits, which the Internet Archive's help page describes. Not every page or date is saved, so a change between two saved copies has no exact date. Pages that are password protected or blocked by the site may be missing. Pages built with JavaScript are often hard to archive and may not display correctly. You can capture a page yourself with the Save Page Now feature, which saves that one page at that moment.

It also cannot tell you what changed. You have to compare two copies yourself, line by line, with a redline. And a page's date is not proof either way, as in the case where SurveyMonkey changed its AI providers on a page still dated November 2025.

How Venpo helps

Venpo watches your vendors' terms, privacy policies, DPAs and other public legal pages and keeps a change history for each vendor, so you can see what a page said before. When something changes, you get a plain-English email with what changed and why it matters.
