Your tools. Your choices.

On pages with affiliate banners, we also record when at least half of a banner remains visible for one second in an active tab. We record its fixed creative and position identifiers, public page path, random tab-session identifier and event time, once per creative per page load. This observation does not prove attention. It does not include the persistent browser identifier, referring hostname or country. We compare it with later banner clicks in the same tab session. Privacy opt-outs and operator exclusions also apply; browsers without visibility-observer support do not send these observations.

For our practical visitor tools, we separately count completed input records, requested text downloads and fixed Helpful or Not yet feedback choices. Completed means the required fields were recorded, not that the answer was correct or an external task succeeded. Loaded fictional examples are excluded from these counts. Tool values, written reasoning and feedback text are not transmitted. Tool interactions do not include the persistent browser identifier or referring hostname.

For product-link clicks, we also record a fixed button location category, such as a tool card or guide shortlist. We do not collect button text. We separately count attempted use of selected local tools and clicks on publication downloads, recording only a fixed tool identifier or published download filename, public page path, random session identifier, and event time. We never collect uploaded filenames, file contents, subtitle text, or tool input values. A download click does not prove a file was saved. Marked verification activity is excluded from normal interaction reports.

Audience measurement

We measure page views and product-link clicks using a random identifier in this tab’s session storage. It expires after 30 minutes without measured activity. A separate random browser identifier in this site’s local storage lasts up to 90 days and measures repeat browsers on this site only. Clearing site data resets it; storage restrictions can leave browser counts unknown. We do not fingerprint or identify unique people, or link browser identifiers across publications. We collect the publication, public page path, product identifier, referring hostname, event time, and an approximate country supplied by Cloudflare. A VPN or network routing can affect country accuracy. Query strings, form inputs, emails, precise location, and raw IP addresses are not stored in our analytics database. Cloudflare processes connection information to deliver and secure this service, including temporary abuse prevention. Events are retained for up to 90 days, with hourly cleanup. We honor Global Privacy Control and browser Do Not Track. Blocking scripts or storage may reduce measurement accuracy. Measurement is for our private editorial reporting. You can opt out through Global Privacy Control or Do Not Track and remove the identifier by clearing this site’s storage.

What this site stores

We use limited audience measurement to improve our guides. We do not add advertising cookies or account registration. An optional email list is hosted by Klaviyo. The cost calculator runs in your browser without transmitting or saving your inputs.

Your document checklist

The document workbench updates locally in your browser. This site does not transmit or store the selected fields or generated notes. Copying places the notes on your device’s clipboard; clipboard access and retention follow your device and browser settings. Printing or saving a PDF uses your browser’s print controls, and you choose the destination. Any copy or saved file remains under your control.

Optional video playback

Video previews use local illustrations. No request to YouTube is made until you click a play button. That action loads an embedded player from youtube-nocookie.com and connects your browser to YouTube. YouTube then receives request information and may process playback activity or use tracking under its own privacy practices. Privacy-enhanced embedding does not mean anonymous playback. You can leave the player unloaded or use the clearly labeled original-source link instead; following that link also connects to the external provider.

Email list

If you join the Peptide Suppliers Compared email list, you leave this site for a subscribe page hosted by Klaviyo. Klaviyo processes your address, consent, and unsubscribe requests under its terms. This publication does not collect addresses in an on-site form. Open the subscribe page.

Hosting and external websites

The hosting provider may process ordinary request information to deliver pages. External links take you to websites with their own privacy practices. A configured affiliate link may use the vendor or network’s referral tracking after you follow it.

Your downloads

Worksheet edits remain wherever you save the file. Do not send private laboratory or purchasing records to this site.
