Terms of Use

Trendosity supports three sign-in methods: (a) Sign in with Google (OAuth — we request only your name, email, and profile photo); (b) Magic link email (one-time link sent to an email address you control); and (c) Passkeys (WebAuthn — Face ID, Touch ID, Windows Hello, fingerprint readers, or hardware security keys). We do not use passwords.

When you enroll a passkey, your device generates a public-private keypair locally. The private key never leaves your device; we never see it. We store only your public credential id, public key, a monotonic signature counter (for replay-attack defense), optional transport hints, and the device label you choose. We never receive biometric data — your face image, fingerprint template, and similar biometric inputs are processed entirely by your device's OS-level authenticator and never reach our servers. By enrolling a passkey you agree to keep the device that holds it under your sole control and to deauthorise the passkey from Settings (or, for synced passkeys, from iCloud Keychain / Google Password Manager / 1Password / your password manager of choice) if the device is lost, sold, or shared.

If your platform (iCloud Keychain, Google Password Manager, third-party password managers) syncs the passkey across your devices, that sync is between your devices and your password manager — Trendosity is not party to that sync and cannot inspect it. You are responsible for the security of any device on which your passkey resides.

• Post content that is illegal, hateful, harassing, defamatory, fraudulent, threatening, intimate or sexual without consent, or otherwise violates anyone's rights.
• Post content that promotes or facilitates harm — physical or financial — to yourself or others, including dangerous goods, weapons of mass destruction, child sexual abuse material, suicide/self-injury content, doxxing, or instructions to commit illegal acts.
• Recommend businesses, services, or products that are illegal where the recipient is likely to act on the rec.
• Impersonate another person, business, or entity, or misrepresent your affiliation.
• Use the Service to send spam, unsolicited promotional content, chain messages, or unauthorized commercial communications.
• No scraping or automated access. Scrape, crawl, spider, harvest, index, cache, mass-export, or otherwise extract content or data from the Service — whether by manual or automated means, headless browsers, residential proxies, screen-recording, OCR, or any other technique — except through documented APIs that we explicitly publish for that purpose with a valid API key issued to you by Trendosity. Rate limits, robots.txt directives, and TOS-Bot signals are binding.
• No reverse engineering. Reverse-engineer, decompile, disassemble, decrypt, deobfuscate, modify, or create derivative works of the Service, our client apps, our APIs, our SDKs, our protocols, our database schemas, or any other component or underlying technology — nor attempt to derive any of the foregoing — except to the extent (and only to the extent) that applicable law expressly forbids waiving this restriction. You may not remove, alter, or obscure any copyright, trademark, or other proprietary-rights notice.
• No unauthorized third-party integrations. Build, distribute, operate, or use any third-party integration, plug-in, browser extension, bookmarklet, wrapper, bridge, MCP server, AI agent connector, mobile-app companion, or other tool that interacts with the Service, reads from or writes to the Service, automates interactions with the Service, or accesses or stores user content from the Service — without Trendosity's prior written approval, which we may grant, condition, deny, suspend, or revoke at our sole discretion. We may require partners to enter a written integration agreement before such use is permitted.
• Bypass, attempt to bypass, or assist anyone in bypassing security features, rate limits, content moderation, access controls, paywalls, privacy settings, or any other protective measure.
• Use the Service to develop a competing product or service, or to train a generative AI model on data accessible to you through the Service (whether your own content or others').
• Upload viruses, worms, malware, ransomware, or other harmful code.
• Interfere with, disrupt, or impose an unreasonable load on the Service or its infrastructure.
• Misuse our APIs in ways that exceed published rate limits or quotas.
• Submit, in any field of the Service, sensitive personal data we have not specifically requested — including bank account or payment card numbers, government IDs, biometric source data (face images, fingerprint templates, voice samples), precise geolocation data, health information, or other categories of data subject to heightened legal protection. (Note: passkey sign-in does NOT submit biometric data — see §1A; it processes biometrics locally on your device.)

DMCA / copyright complaints. If you believe content on the Service infringes your copyright, send a notice to our designated agent at our contact form with: (a) your physical or electronic signature; (b) identification of the copyrighted work claimed to be infringed; (c) identification of the material and its location on the Service; (d) your contact information; (e) a statement of good-faith belief that the use is unauthorized; and (f) a statement, under penalty of perjury, that the information is accurate and that you are the owner or authorized to act on the owner's behalf. Counter-notices may be sent to the same address. Repeat infringers will have accounts terminated.

Please read this section carefully — it affects your legal rights.

(a) Informal resolution. Before filing any claim, you agree to try to resolve the dispute informally by writing to our contact form with a description of the claim and the relief sought. We'll do the same before bringing a claim against you. The parties will negotiate in good faith for 60 days before either side may bring a formal claim.

(b) Binding arbitration. If we can't resolve a dispute informally, you and Trendosity agree that any claim, dispute, or controversy arising from or relating to these Terms, the Service, or our relationship will be resolved exclusively by final and binding individual arbitration administered by JAMS under its Streamlined Arbitration Rules, in New York County, New York, before a single arbitrator. Arbitration is conducted in English. The arbitrator has exclusive authority to resolve any dispute about the interpretation, applicability, enforceability, or formation of this agreement to arbitrate, including any claim that all or part of it is void or voidable.

(c) Class-action waiver. YOU AND TRENDOSITY AGREE THAT EACH OF US MAY BRING CLAIMS AGAINST THE OTHER ONLY IN OUR INDIVIDUAL CAPACITY AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS, COLLECTIVE, REPRESENTATIVE, OR PRIVATE-ATTORNEY-GENERAL ACTION OR PROCEEDING. The arbitrator may not consolidate more than one person's claims, may not preside over any form of consolidated, representative, or class proceeding, and may award relief (including monetary, injunctive, and declaratory relief) only in favor of the individual party seeking relief and only to the extent necessary to provide relief to that individual.

(d) Exceptions. Either party may bring an individual action in small-claims court if the claim qualifies and remains pending only there. Either party may seek injunctive or other equitable relief in a court of competent jurisdiction to prevent actual or threatened infringement of intellectual-property rights.

(e) Opt-out. You may opt out of binding arbitration and the class-action waiver by sending written notice to our contact form within 30 days of first accepting these Terms. Your notice must include your name, the email associated with your account, and a clear statement that you are opting out of arbitration. Opting out will not affect any other provisions of these Terms.

(f) Severability. If the class-action waiver is held unenforceable as to a claim, that claim alone is severed from arbitration and litigated in court; the rest of this section remains in force.
