How We Test & Verify

Quick answer

How All Day Toolkit builds, tests and fact-checks: local-first processing, automated tests, sourced reference data and visible last-verified dates.

How we build and verify

1
Local-first. Wherever possible, tools process your files in your browser — nothing is uploaded.
2
Tested. Every tool is covered by automated unit and end-to-end tests across Chrome, Firefox and Safari (desktop + mobile).
3
Sourced. Reference facts cite primary/official sources and carry a visible “last verified” date.
4
Honest. We label where each tool runs and never claim local processing for something that uploads.

We never collect file contents, file names, image metadata or generated output in analytics or logs.
