Privacy notice

Last updated: 22 October 2026

This notice explains what happens when you follow one of our short links: an address such as …/l/AbCd1234EfGh56, or one on a business's own domain such as go.example.com/AbCd1234EfGh56, that a business using Better Sell High put in a post, a message or a QR code. It leads you on to the page that business chose (after a date the business may set, to another page, or nowhere). It also explains, further down, the website analytics a business may add to its own website.

What we count

• For each short link and each day (in UTC): how many times it was followed by a person (clicks).
• Separately, how many times it was fetched by a machine: a link preview (in a chat or social network), a search engine crawler, or a request that only checks the link (bot hits).

These are two numbers per link and day, shown to the business that created the link and, to operate and support the service, to us. On their own they do not say who clicked. But if a business sends a link to one person only, its count can show that this person (or someone they passed it to) followed it.

Coarse statistics, if the business turns them on

They are off unless an administrator of the business turns them on. Then, for each click by a person (never for bot hits), we also add one to four daily totals of that link:

• the country, as our hosting provider derives it from the connection (we never see or keep the IP address for this);
• the kind of device: mobile, tablet or desktop;
• the browser family, such as Chrome, Safari or the LinkedIn app;
• the site or app the click came from, as its domain or app name only (such as linkedin.com), or “direct” when there is none.

These are separate totals per link and day: nothing links a country to a device or a browser, or one click to another, and nothing is stored per click or per person. Rare values are grouped as “other” beyond 50 a day. They are kept for 400 days, and deleted when the business turns them off or deletes the link.

What we never store in our database

• Your IP address, not even in a scrambled (hashed) form. (Website analytics keep a daily visitor number instead: see below.)
• Cookies: following a short link sets none and reads none, and we store nothing on your device.
• Your full browser identification (user agent). We only look at it while answering, to tell people from link previews and crawlers (and, with coarse statistics on, to count the device kind and browser family).
• The page you came from (the referrer): with coarse statistics on, only its domain is counted, never the full address. We also ask your browser not to pass it on to the page you are sent to.

So that one address cannot inflate the counts or flood the service, the server that answers keeps a scrambled form of your IP address (for newer IPv6 addresses, of its network part) in its working memory, under a key made at random every day and never saved. Past about 60 visits a minute from one address, further visits are still sent on but not counted; only past about 600 a minute does that server ask the address to slow down instead of sending it on. While that server runs, it removes the scrambled address about two minutes after your last visit. If the hosting platform pauses the server in between, it is removed when the server runs again or is shut down. It is never written to our database.

What our hosting provider records

Our pages, short links and website analytics are served by our hosting provider, Vercel. Like most hosting platforms, its servers record each request in technical logs: your IP address, your browser identification (user agent), the page you came from (the referrer), the address you asked for (for a short link, its code; for website analytics, our script's address) and the time. Together, these can show that a particular device followed a particular short link. We use these logs only to run and secure the service, never to count clicks or to follow people. Vercel keeps them for between one hour and 30 days, depending on the hosting plan.

Why

Businesses want to know whether the links they share are used, so they can tell which posts work. That is our legitimate interest, and the business's. We meet it with counts only: our database holds nothing that identifies you or your device, we build no profiles, and do not follow anyone from one site to another. Coarse statistics are only totals of a few broad categories, which tell a business where its readers come from in general, never who they are.

Once a day, our server also checks that the page each short link leads to still answers, so the business learns when a link is broken. That check visits the business's page, never you, and uses nothing about readers.

How long

Daily counts are kept for 400 days, then deleted. When a business deletes a short link, its counts are deleted with it, and the address stops working.

Website analytics

A business using Better Sell High may add our small script to its own website to measure its audience: how many people visit, which pages they read, which sites and campaigns brought them, and how many reached a goal the business set (such as a thank-you page). The business decides to use it and should say so in its own privacy notice; we run it for that business only and never combine one business's figures with another's.

• The script sets no cookie and stores no identifier on your device. If you asked a site not to measure your visits (with the site's own opt-out, which calls bshAnalytics.optOut()), your browser keeps that one choice, so it can be honoured; nothing else is written.
• Nothing is sent when your browser asks sites not to track you (Do Not Track or Global Privacy Control) or when it is run by a program. Requests from search engines, link previews and other robots are not counted.
• For each page view or event we keep: the website, the page's path (never its query string, except the campaign labels utm_source, utm_medium, utm_campaign, utm_term and utm_content), the name of the site you came from (not the page), the time, and a visitor number. Only if the business turned it on: your country (from your IP address, as our hosting provider reports it), your kind of device (computer, phone or tablet) and your browser's name, without its version.
• The visitor number lets us count one person once a day. It is computed from the website, your IP address and your browser identification with a secret that changes every day (UTC) and is deleted when the day ends. After that, nobody, us included, can tell whether two days' visits came from the same person, and the same person gets a different number on every website. Your IP address and browser identification themselves are never stored.
• We never link these visits to a name, an email address or a contact the business holds. The business sees totals per day, page, source, campaign and goal, and, side by side, how many of its new contacts came from the same campaigns, counted from what those contacts told it (for example a form), never from your visit.

The individual page views and events are deleted after 30 days. The daily totals made from them are kept for 25 months, then deleted. When a business removes a website, everything recorded for it is deleted at once. The same limit on visits per minute as for short links applies, in the server's working memory only. This measurement is exempt from consent under the French data protection authority's (CNIL) conditions for audience measurement: it serves only the website's own statistics, produces anonymous figures, does not follow you across sites, and is not combined with other data.

Who to contact

Better Sell High is run by an individual as a personal project. For any question about this notice, contact whoever shared the link with you, or the website you visited; they can reach us. You can also complain to your data protection authority.
