Privacy policy

Policy of 2026-10-03. See also the terms of use.

The short version

Cupel never asks for anything about your accounts or your money on the public site. To browse, it keeps nothing about you. If you sign up for a Cupel account or sign in to submit a strategy, it keeps your e-mail address, the province or state you live in, and what you accepted. A strategy you submit is published without your name or address. Cupel does not sell information about anyone and shows no advertising.

What Cupel keeps, and why

• Browsing. No account is needed and nothing about you is stored in Cupel's database. The servers that deliver the site keep ordinary request logs (the address of your connection, the page, the time). The country shown to you is chosen from your own choice, else the country of your connection as the hosting layer reports it, else your browser's language; only your own choice is remembered, in a cookie.
• Signing up for a Cupel account. Your e-mail address, your country and province or state, the licence you accepted and when. You receive an API token to use with the app; Cupel keeps only a scrambled form of it (a hash), when it was last used and how many requests it has made, to apply the request limit. The app is open source and runs on your own computer; your accounts and balances are never sent to Cupel.
• Signing in to submit a strategy. You sign in with Google. Google tells Cupel your e-mail address, your name and the link to your profile picture, and Cupel keeps those with the sign-in's tokens so it knows it is you next time. Cupel also keeps the province or state you give, that you said you are 18 or over, and the licence and publication terms you accepted, with their dates.
• What you write in the editor. Your description of a strategy, the questions and answers that follow, the rule that results and how much of the translation service was used. These stay with your sign-in; only you see your drafts.
• What you submit. The strategy's name, source and rule, your description, the terms you accepted, when, and what became of it. The rule and its results are published to everyone; that you were the one who submitted it is not. A request to take a strategy down is kept with its reason.
• What you post as feedback. A topic or a reply you write, your votes, the topics you follow, a flag you raise with its reason, and the name you chose to be shown by, if any. Topics and replies on the public site are published to everyone under that name or as “a Cupel user”; your e-mail address and your Google name are never shown, and who voted is not shown. A post that is hidden or removed stops being shown and is kept, with who hid it and why.
• Using Cupel through an advisory firm. On a firm's own address, the firm's users, their clients' accounts and the portfolios built for them belong to that firm, and each firm sees only its own. Cupel keeps them for the firm, logs every change to them, and its operator looks into a firm's records only for a stated reason, which is logged. Ask the firm about its own privacy practices.

Who else receives anything

• Google, for sign-in. Google confirms who is signing in. Cupel sends Google nothing about what you do here.
• Google, for translation. The words you type to describe a strategy are sent to Google's Gemini service, in the United States or wherever Google processes them, to be turned into a rule, and to Google's search to look up what the described strategy is. Your name and address are not sent. Do not put personal information in a description. If Cupel switches on the sorting of feedback, the words of a topic posted on the public site are sent to the same service to be sorted, never who wrote it.
• An e-mail service. Sign-in links, registration links, the note that a submission has finished, and the mail about feedback topics you voted on or follow (each with a link that stops it) are sent through Amazon Web Services in the United States. Those messages carry your e-mail address and nothing about your money.
• Hosting. The companies whose servers run the site and its database process what passes through them on Cupel's behalf.

Cupel does not sell or rent personal information, does not share it for advertising, and gives it to no one else unless the law requires it.

Where it is kept

Cupel's database, with everything listed above, is kept in Canada. The two services above that work in the United States receive only what is said there.

Cookies

• A sign-in cookie, only once you sign in. It lasts 12 hours, works on the address you signed in on and no other, and cannot be read by scripts.
• Preference cookies, kept for a year: the country you chose, and the theme if you changed it.

There are no advertising cookies and no analytics: nothing on the site tracks or profiles visitors.

How long it is kept

A registration is kept until you ask for it to be closed. A sign-in session ends after 12 hours. A submitted strategy that is taken down stops being shown, but its runs and the record of the attempt are kept, without your name, because every other strategy's rating counts them.

Your choices

You may ask what Cupel holds about you, have it corrected, and have your registration closed and your address removed. A strategy you submitted can be taken down from the submit page, and a feedback post of yours removed by asking beside it. You may also complain to the privacy regulator where you live; in Canada that is the Office of the Privacy Commissioner of Canada or your province's own.

Children

Signing up for an account and submitting strategies are for people 18 or over. Cupel does not knowingly keep information about anyone younger.

Changes

This policy changes when what Cupel does changes. The date at the top says which policy this is.
