Privacy
The short version: your quiz answers and any guide you save are yours. Your answers are sent to our server only to work out your results, and the server does not keep them. Unless you save a guide, they stay only in the browser tab you are using. A guide you save is stored so the site can show it back to you, and you can delete it. We do not sell them or share them for advertising. EVER.
Effective date: October 21, 2026
This covers quiz answers, your email if you sign in, and a few technical records.
Quiz answers. These include the health conditions and medicines you select in Build My Guide, and your safety answers. That is health information about you, and we treat it as the most sensitive thing here. Your answers are sent to our server only to work out your results, and the server does not keep them. Unless you save a guide, they are kept only in the browser tab you are using. A saved guide keeps some of them, but not your health and safety answers (see Saved guides below). Some choices, such as the interests you pick, also reach our analytics tools, as described below.
Your account. If you save a guide or sign in, we keep your email address. We use it to sign you in and to send things you ask for. There is no password: you sign in with a link we email you.
Free-guide email. If you request a free guide by email, we keep an encrypted delivery address and a keyed, one-way email code to complete your request. Those contact fields are scheduled for clearing 365 days after the claim by our daily cleanup. An outage can delay cleanup. Campaign attribution, consent and legally required transaction records are handled separately and may remain longer. Getting the free guide never requires optional marketing consent.
Abuse protection. When you ask to save a guide, sign in or have the Starter Map emailed, we keep a keyed one-way code made from your IP address, not the address itself, so we can limit how many requests come from one place. It is deleted after about 2 days.
Printed cards. If you arrive from one of our printed cards, your browser keeps that card’s short code for 30 days, so a later visit from the same card still counts toward it. It never includes your answers or anything you type. The code is sent with some analytics events, such as starting the quiz.
Server logs. Like any website, our host Vercel keeps standard request logs, which include the web address of each page requested.
Purchases. If you buy a paid guide, we keep a record of the order: what you bought, the price, any discount, the currency, the date, its status and Stripe’s reference for the checkout. If you buy without signing in, we also keep the email address you paid with, encrypted, so you can get to your download later. Card details never reach this site.
These are the companies that handle your data for features that are live today.
Every company below handles data for a feature that is live on this site today. If that list changes, this page changes with it.
- Vercel: hosting and serving the site.
- Neon: the database your sign-in account and saved guides live in.
- Proton Mail: sign-in links and any email you ask for.
- Google: Google Analytics, loaded through Google Tag Manager. See below.
- Microsoft: Clarity, which records how pages get used. See below.
- Umami: page counts without cookies. See below.
- Stripe: payment for paid guides. Checkout happens on Stripe’s own page. Stripe receives your card details, your email address for the receipt, your billing address to work out sales tax, and which guide you are buying.
- Amazon Web Services: Amazon SES sends the 30-day course lessons. It receives your email address and each lesson, and tells us whether each one was delivered, bounced or marked as spam. We stop sending to an address if a lesson bounces permanently or is marked as spam.
AI writing services are not active on the public site today. We will update this page before we turn them on for visitors.
Two of these tools set cookies, and you can say no to both.
Three tools, and a counter of our own, show us how the site gets used: which pages people read, where they stop, and what confuses them.
None of them receive your name, email address, phone number, age or date of birth. They do not receive the health conditions or medicines you select, or your safety answers. They also do not receive the words you type into a search box, saved guide ids, sign-in links or other private addresses, or the contents of a saved guide. The interests you pick can be health-related, so we treat them with care: we do not sell them, and they are not used for advertising or to build advertising audiences. Google and Microsoft do see which pages you open, including which compound pages, and which buy links you click. A buy link also tells US Precision Peptides that you came from Learn Peptides, from which page and for which compound.
- Google Analytics counts visits and pages, and records what people choose and do: the interests picked in Build My Guide, the needle preference, which results and compounds are shown or opened, library and route filters, compare choices, and clicks on buy links. For health-sensitive interests, such as sexual health, fertility, mood, gut, weight, immune or surgery topics, it gets only the broad category, never the exact topic. It also records how fast pages load for you. It sets cookies whose names start with
_ga. Its advertising features, Google signals and ad personalization are off. - Microsoft Clarity records clicks, scrolling and what is on screen so we can replay how a page was used, including the interests you pick, filters and compare choices. Clarity stops recording while the safety and health questions are on screen, so those answers are not captured at all. It does not record the results page for anyone, so your results and the notes your health answers add to them are not captured either. Email fields and anything you type into a search box are blanked out of the recordings. Clarity does not run on My Guides or on sign-in and access pages, and will not run on personalized downloads or checkout pages. It sets cookies such as
_clckand_clsk. - Umami counts page views without cookies and without keeping anything that identifies you. When someone opens one of our earlier short links (the ones printed on cards and guides), clicks a buy link or signs up for the course, our server tells Umami directly. Only the page, the kind of action, which link or compound it was about, the page you came from, and your browser’s language and type are sent. Your IP address is not sent. If your browser sends a Global Privacy Control signal, nothing is sent.
Our own visit counter. We also count visits ourselves, with no cookies and no outside company. When you open a page, our server makes a one-way code from your internet address, your browser type and the date. The code changes every day, so it cannot follow you from one day to the next. We never store your address or your browser details themselves. With that code we keep the page address (never a search or anything you type), the website you came from, the campaign tag on the link if there was one, your country, whether you are on a phone, a tablet or a computer, and how long the page was on your screen. If you sign up for the course during a visit, that visit is marked as a signup. The mark holds no email address, name or other detail about you. If you click a buy link during a visit, that visit is marked too. These records are deleted after about 90 days. We keep only daily totals after that. If your browser sends a Global Privacy Control or Do Not Track signal, nothing is counted. Where analytics waits for your yes, the counter waits too. Elsewhere it runs even if you turn the other tools off, because it keeps nothing that can identify you.
Course email opens and clicks. Our course lessons include a tiny image and tracked links. They tell us whether a lesson was opened and whether a link in it was clicked. We record only the first open and the first click for each lesson we send, nothing more. We keep each mark for about 90 days, then delete it, and we delete them sooner if you leave the course. We look at them only as totals for each lesson, never person by person. Some mail apps load images on their own, so open counts are only approximate. The unsubscribe link is never tracked.
Door-tag QR counts are separate. When an eligible production door-tag QR link is opened, Learn Peptides adds one to an hourly total for that printed batch and side. That table stores the QR code, the hour and the count. It does not store a raw IP address, user agent, referrer, query string, cookie value or identity. Repeat opens can count again, and automated traffic can sometimes be missed or counted, so these totals are link opens, not unique people or exact physical scans.
Google Analytics and Clarity use cookies, so where you are decides when they start. In the EU, the UK and a few other places, none of the three tools load until you say yes. In US states with their own privacy laws, Google Analytics and Clarity start on your first visit, and you can switch them off. Umami uses no cookies. Outside the EU, the UK and those other places, it runs for everyone, even if you switch the other two off. If your browser sends a Global Privacy Control signal, we treat it as a no on every visit, even if you said yes before. Then none of the three tools load.
Your cookie choice itself is saved in your browser for up to a year, so we do not ask on every visit. Where Umami is running, it counts which choice was made. A cookie named lp_consent_mode lasts one day and tells the site which of these rules applies where you are.
For door-tag QR links, we also use a small first-party preference cookie named lp_qr_preference. It exists only so the QR redirect and our buy links can honor the analytics choice already stored in your browser. Its value contains the consent-policy version, whether analytics is allowed and whether that choice came from you, your browser privacy signal or the site default. It contains no random visitor identifier and is not used to recognize you across sites. It is limited to /r and /go links and expires with the stored analytics choice. Door-tag counting also honors Global Privacy Control and Do Not Track.
Scanning the front of a door tag can also set a cookie named lp_qr_ctx. It remembers which batch of door tags you scanned, never who you are. If you then shop at our partner, US Precision Peptides, through a link on our site, the link tells them which batch brought you, so that batch gets the credit. The cookie expires within a day. It follows your cookie choices: if you turn analytics off, or your browser sends a privacy signal, it is not set or used.
We sometimes show two versions of a page, such as the homepage, to learn which one helps more people. If analytics is on for you, a cookie named lp_exp keeps you on the same version for up to 30 days. It holds only the test name and a version letter. It has no ID. A second cookie, lp_analytics_choice, copies your cookie choice so our server can follow it. It lasts as long as that choice. Google Analytics gets the test name and version when you see the page and when you click Build My Guide. If analytics is off, or your browser sends Global Privacy Control or Do Not Track, you see the usual page. No version is saved, and nothing about the test is sent.
You can change your answer any time: .
Saving is optional; here is what we store, how we protect it and how long.
Saving a guide is optional and free. The quiz and your results work without an email address. Unsaved quiz answers stay only in the browser tab you are using, and clear when you close it or start a new guide. A guide you choose to save is stored, as described here.
What is stored when you save.
- Your email address, so you can sign in. Our sign-in system uses it.
- The topics you selected.
- The results you were shown, and the health-related cautions shown with them.
- Your needle preference.
- The date and version information.
- Your place in the guide.
What is not stored. Your full health questionnaire answers, meaning the safety and health questions. A saved guide can still show health-related interests, so we treat it as sensitive.
How it is protected. Guide contents, titles and reading position are encrypted in our database. Your sign-in account stores your email address separately. A keyed hash, a one-way code made from your address, is used to match access requests.
Signing in. There is no password. For My Guides, we email you a one-time link that lasts 15 minutes, and you confirm on the site before it opens. Your browser session ends 7 days after you sign in. Access to saved guides also requires email verification within the past 30 days. Deleting all saved guides requires verification within the past 24 hours.
How long it is kept. An unconfirmed save request is held for up to 24 hours. Saved guides remain available for 12 months after you last open or update them. You can delete one guide or all guides from My Guides. Deleted guides become unavailable immediately. Expired records are removed from the active database by the next successful daily cleanup, with a fallback during visits. Technical failures can delay removal but do not restore access. After removal from the active database, encrypted copies may remain in the database provider’s recovery history for up to one further day. Deletion does not remove copies you printed or downloaded, your sign-in account, or the minimal records needed to respect your email choices and completed deletions.
Emails. When you ask, we send the link to sign in or save, a one-time confirmation of your first saved guide, or a link to your guide when you ask us to email it. Ongoing emails are separate and optional, and the box for them starts unchecked. If you choose them, that choice is recorded. Our 30-day email course sends only to people who confirm their sign-up. Every email has a one-click unsubscribe. You can withdraw at any time in My Guides, under Email Preferences.
Who handles it. The same services named above: Vercel for hosting, Neon for the database and Proton Mail for email.
What we do not do. No analytics or session replay tools load on My Guides or on its sign-in and confirmation pages. Saved guides are not used for advertising and are not shared with US Precision Peptides.
If you join, we keep your address encrypted, and you can stop at any time.
If you join, we ask you to confirm your email first. We keep a record of your request and confirmation, a keyed code made from your address, and your address in encrypted form so we can send the lessons.
If a tagged link brought you here, such as one on a printed card, we keep that link's campaign tag with your sign-up. The tag names the link, not you.
One lesson a day for 30 days, including weekends; some lessons include relevant Learn Peptides and US Precision Peptides resources or offers. You can pause or unsubscribe at any time; unsubscribing erases your encrypted address from the course right away.
An unconfirmed request is deleted after about 48 hours. We keep your encrypted address until 365 days after you finish, pause or last change the course, then delete it. We keep the record of your choices, including an unsubscribe, so we can keep respecting it.
Delete your account yourself in My Guides, or email us if you cannot sign in.
You can delete your account yourself. Sign in to My Guides and choose Delete my account under Account and privacy. Your sign-in account, all your saved guides and any free guide sign-ups made with your email address are deleted right away, any optional emails stop, and unused sign-in links stop working. This cannot be undone. Copies you printed or downloaded are not affected. To protect your account, you may be asked to confirm your email again first.
Apart from purchase records (below), we keep only the minimal records needed to respect your email choices and completed deletions. These are a keyed one-way code made from your email address, not the address itself, and a note that each deleted guide was deleted. Backups roll off on their own schedule, so a copy may stay in them for a short time before it ages out.
If you cannot sign in, email info@learn-peptides.com and we will delete it for you.
If you made a purchase, some transaction, payment, refund, dispute and tax/accounting records may need to be kept for legal, accounting, fraud-prevention or tax obligations even after account deletion. Those records are not used to restore deleted saved guides or marketing permission. When you delete your account, purchases in it are kept only as those records: they are no longer linked to your account, our copy of your email address is removed from them, and their downloads stop working. A new account does not bring them back. A payment that goes through after you delete your account is kept the same way and gives no access.
We are not a healthcare provider, so a doctor’s office protections do not apply here.
Learn Peptides is not a healthcare provider, and this is not a medical record. Your information here has none of the protections a doctor’s office would give it. That is one more reason not to use this site in place of a doctor.
