Privacy Policy Diff Checker

Sample: old vs. new policy excerpt

Example shown — replace it with your own two policy versions.

Old: "We do not share your data with third parties."
New: "We may share your data with select partners for marketing purposes."

Result

1 material change flagged: data sharing clause weakened

How it works

  1. Paste the old and new policy text.
  2. Differences between the two are identified.
  3. Get a flag on changes that look materially significant.

The method

Text differences are compared and checked against patterns commonly associated with meaningful privacy changes, like new data sharing or retention language.

FAQ

What counts as a "material" change?

Changes that affect how your data is used, shared, or retained — like new third-party sharing, new data collection, or changed retention periods — as opposed to purely cosmetic wording changes.

Does this compare legal language automatically?

It compares the text you paste and flags likely-material differences; always read the full updated policy yourself for anything flagged as changed.

Is this legal advice?

No — this helps you spot changes worth reading closely, but it isn't a substitute for legal review of a policy's terms.
