THE IMPACT
ARCHIVE
OpticQuiz keeps no analytics on the people who use it. That is a deliberate choice, and it has a cost: without tracking, the project cannot show that it helps anyone.
So this page asks instead. Everything below was volunteered by a person who clicked a button, and every word published here was published because its author explicitly said it could be — and can be deleted by them at any time, with no account.
It is not a testimonials wall and it is not a sample. The people who answer are self-selected, and self-report is weak evidence. It is published anyway, in full, including the answers that say no, this did not help — because a record you can check is worth more than a claim you have to trust. How it is collected and what is kept →
THE COUNTS
Live from the archive. Each figure is a count of rows a human submitted — there is no seeding, no estimate, and no rounding.

THE STORIES

ADOPTION
Downloads and installs, fetched live from each registry's own public API. The source URL is printed under every number so you can re-run the request yourself. A blank means that source could not be verified right now — it is never replaced with an estimate.

HOW THIS IS COLLECTED
The block that asks “did this help you?” appears on OpticQuiz tools. It is the same code everywhere — /assets/oq-feedback.js — and it works like this:
Nothing is sent until you press a button
There is no beacon on page load, no page-view record, no cookie, and no identifier of any kind. If you never click, the archive never learns you existed.
Two locks before anything is published
Your words appear here only if you ticked the publish box and a human then approved the record. Skip the box and your answer is only ever counted, never quoted.
Consent you can take back
Every submission returns a withdraw code. Entering it below deletes the record permanently — from the archive, from the counts, and from every future export. No account, no email, no reason required. Withdraw a record →
What is stored
Exactly the fields you filled in, plus the date at day precision (a timestamp to the second is a fingerprint; a date is a fact) and which tool you were using. No IP address is stored against a submission. An email is stored only if you typed one, is never published, and is never added to any list.
The one thing that touches your IP
To stop a script flooding the moderation queue, the server counts submissions per hour against a salted SHA-256 hash of the connection's IP. The hash cannot be reversed to an address, is never stored next to a submission, and is deleted when the hour ends. It is written down here because a privacy claim with an undisclosed exception is a lie. The code is public.

Citing it

Retrieved <date>. Method: doi.org/10.5281/zenodo.21310578If you cite it, cite the caveat with it: self-reported, self-selected, unverified by any third party, and not a clinical outcome measure. It documents that specific people say specific tools helped them. That is all it documents, and it is enough.
WITHDRAW A RECORD
Enter the record id and the withdraw code you were given. The record is deleted immediately and permanently.
ADD YOURS
If an OpticQuiz tool helped you — or wasted your time — say so here. Either answer is useful; only one of them is flattering, and both get published.
