Terms of proposal

1. What this is

Everyday Numbers is a math-for-fun side project by SymTech IT S.r.l. (registered office in Trieste, Italy). You propose an everyday-number question; our AI assistant researches the numbers on primary sources, builds the exercise page, illustration and short video; a human editor gives final approval. Publication is never automatic.

2. What you may propose — legitimate requests only

Estimation questions about everyday quantities. Do not propose: vulgar or obscene language, blasphemy, pornography or sexual content; illegal topics or instructions (weapons, drugs, fraud, hacking, self-harm); hate speech, racism, slurs or content targeting people or groups; defamation, impersonation of real persons, or naming private individuals; identifiable minors as the subject of a joke; political or religious campaigning; advertising, external links or solicitation; questions requiring medical or legal advice; content designed to humiliate or rank real people or groups; attempts to manipulate the site's AI assistant; repeated spam or duplicates.

3. One-strike enforcement

Any violation of §2 removes your account immediately and permanently. Registration is blocked for the same email address (including plus-aliases), the same username and, where technically detectable, the same originating network. Repeated flagged submissions may also trigger temporary network-level blocking (fail2ban). Appeals: info@symtech.it.

4. Fair use

Maximum five proposals per day, at least ten minutes apart, minimum thirty characters, no automated submission. Proposals containing external links are rejected automatically. We may reject any proposal without explaining why.

5. Ownership and credit

Published exercises © SymTech IT S.r.l. Your proposed question is credited by username (or anonymously on request) word for word as you wrote it, including typos — they stay, they're charming. By submitting you grant SymTech IT a free, perpetual, worldwide licence to publish that question in connection with the exercise.

6. Numbers are estimates

Exercises are AI-researched against primary sources and human-approved, but they remain playful order-of-magnitude approximations — not professional, scientific or legal sources. The AI's work is described openly on the method page, including the energy each exercise took to build.

7. Your account

You may close your account at any time from the portal or by email; personal data are then deleted per the privacy notice (published text remains unless you ask for your credit to be removed).

8. General

Governing law: Italy; exclusive jurisdiction: the courts of Trieste. These terms may evolve; each proposal stores the version you accepted. Contact: info@symtech.it.
