About
Clip Contract is a local pasteboard regression lab for Mac developers and QA teams. Save separate named cases from known-good copies, compare the same values from later builds, and retain the latest 25 labeled checks per case. The comparison reports missing formats, added formats, changed payloads, exact matches and unreadable data.
Getting started
- Copy a representative value from a known-good app build.
- Open Clip Contract, name your test case and choose Save Clipboard as Baseline.
- Copy the same test value from the build under test. Add a label and choose Compare Current Clipboard.
- Switch among saved checks or choose Export Case Report to save a JSON diagnostic.

Frequently asked questions
What is stored in a contract case?
Format identifiers, byte sizes, local SHA-256 equality digests, timestamps, the case name and check labels. macOS does not expose the original copying application, so current captures do not attribute it. Older foreground observations are labeled as legacy metadata. The case does not retain clipboard values.
Does the app record everything I copy?
History recording is off on a fresh install. Capture History provides an explicit Record History switch. When enabled, that archive retains the primary text, image or file reference for reproduction. Copies marked private, transient or automatically generated are excluded.
What does a report include?
Case names, check labels, timestamps, format identifiers, byte sizes and comparison results. Clipboard values and equality digests are omitted. Names and labels are user text, so review them before sharing a report.
Does Clip Contract send my clipboard anywhere?
Contract cases and optional capture history stay on this Mac. There is no developer account, analytics or sync service. Apple handles and verifies the optional purchase through StoreKit.
