Privacy Policy

Effective date: August 5, 2026

1. Who we are, and the short version

Learn Pass Grow (learnpassgrow.com) is operated by Cosyslabs Inc., an Ontario, Canada software studio, which is the data controller for anything described on this page. Questions and requests go to [email protected].

The short version: your grades never leave your device, because the calculators do not have anywhere to send them. Tracking is switched off until you accept it. We ask for a phone number nowhere on this site. We do not sell personal data, and we have almost none to sell — the only personal information we can hold at all is an email address somebody typed into a form on purpose.

2. Your grades stay on your device

Every calculator, study tool, and practice test here runs entirely in your browser. The figures you type — current grades, exam weights, test scores, GPA and credits, attendance, target grades — are never transmitted to our servers or to anyone else. There is no account system, no server-side record of what you calculated, and no mechanism by which we could see it. Closing the tab is enough to walk away clean.

This is a property of how the site is built rather than a policy we apply to ourselves. The grade engine is a set of pure functions with no network access at all, and an automated test walks the entire source tree on every run to confirm that only four modules can reach the network: the feature-flag file, the newsletter form, the contact form, and the study assistant. Three of those four are things you have to type into and submit deliberately. If a fifth ever appears, the build fails.

3. What your browser keeps for you

A few things are saved so the site remembers you between visits. All of them live in your own browser’s storage on your own device, all of them are named with an lpg- prefix so they cannot be confused with another site’s, and every one of them disappears when you clear your browser data:

• Light or dark mode, and which grading system you picked.
• Tools you pinned as favourites.
• Your Practice-Test Ledger entries — the score you predicted, the score you got, and the date.

The Ledger deserves saying plainly, because it holds the most sensitive thing on the site: a record of how you have actually been performing. It is localStorage only. It has no sync, no backup, and no account behind it, and it never reaches the network — a test asserts that the module cannot make a network call of any kind, so the promise survives people forgetting it. The consequence is worth knowing in advance: your history lives in one browser on one device, and clearing that browser’s data deletes it permanently. The Ledger has a CSV export for exactly that reason, and it carries no advertising.

4. Analytics and advertising load only after you consent

Until you accept the cookie banner, no analytics or advertising script loads at all. If you accept, we use:

• Google Analytics 4 — which pages are visited and which tools are used, with IP anonymisation.
• Microsoft Clarity — aggregate session heatmaps.
• Google AdSense — advertising, which never appears inside a calculator panel, on the Practice-Test Ledger, or on the study kit page.

Declining means no tracking cookies and no personalised advertising. One thing is worth spelling out because it is unusual: when a practice test is scored, the analytics event records a coarse band rather than your result. Your actual score is not sent anywhere.

5. We do not sell your data

We do not sell, rent, or trade personal information, ever. We are not a lead-generation business: nothing you enter into a calculator or a practice test is packaged, scored, or passed to a school, a course provider, a recruiter, or anyone else.

6. No phone numbers

There is no telephone field anywhere on this site — not in the contact form, not in the newsletter, not in any tool. You will never receive a call or a text message because you used Learn Pass Grow.

7. The newsletter is double opt-in

If you ask for the free study kit, you give us an email address and nothing else. It is strictly double opt-in: after submitting the address you must click a confirmation link before anything is sent, so an address typed in by someone else cannot subscribe you. We store the address and whether it was confirmed, use it only to send the kit and the occasional note about a new tool, and put a one-click unsubscribe link in every message.

8. The contact form and the study assistant

If you use the contact form, we receive the name (optional), email address, subject, and message you typed — nothing else — and use them only to reply. The form is protected by Cloudflare Turnstile, which processes technical signals to tell humans from bots under Cloudflare’s own privacy policy.

The study assistant, where it is switched on, sends the question you type to our server so it can be answered. Treat it like an email rather than like a calculator: the calculators keep your figures on your device, and a chat message by its nature has to be sent somewhere to be read.

9. How long we keep things

Contact messages are kept only as long as it takes to deal with them and a reasonable period afterwards in case the conversation resumes. A newsletter address is kept until you unsubscribe, at which point it is removed. Anything saved by a calculator or the Ledger is not ours to keep or delete — it is on your device, under your control, and clearing your browser data removes it.

10. Your rights

You can ask us what we hold about you, ask for it to be corrected, or ask for it to be deleted, and you can withdraw consent to analytics and advertising at any time by clearing your cookies for this site and declining the banner. Write to [email protected] and we will act on it. In practice these requests are short conversations, because for almost everyone the only thing we hold is an email address, and for most visitors we hold nothing at all.

11. Younger students

The calculators are usable by anyone and require no account, no name, and no age, which is the design we want: a school student can work out a grade here without identifying themselves to us in any way. We do not knowingly collect personal information from children. If you believe a child has submitted an email address to us, write to the address above and we will remove it.

12. Links to other sites

Certification pages link to the certifying body’s own materials, guides link to the research they cite, and some pages link to other sites in the Cosyslabs network. Those sites have their own privacy policies and this one does not cover them.

13. Changes to this policy

If this policy changes materially, the effective date at the top changes with it. Since almost every claim here is enforced by a test rather than by memory, a change to what the site does is the thing that would force a change to this page.
