Privacy Policy
Effective: 2026-05-20 · Last updated: 2026-05-20
Onym is built around a single principle: your data stays on your device. We don't run user accounts, we don't keep a database of your names or birth dates, and we don't track you. This page explains exactly what that means in practice.
1. What we collect
Nothing on our servers. Onym has no account system and no central database of users. You don't sign up, you don't sign in, and we never receive a name, birth date, or naming session.
2. What stays on your device
The information you enter during a naming session — your Chinese name, birth date (optional), region, gender preference, and vibe tags — is stored locally on your device using your operating system's private app storage. Your naming results live alongside it. None of this leaves the device except as described in Section 3.
You can wipe all of it in one tap from Settings → Delete all my local data.
3. How the LLM naming engine works
When you generate a paid Cosmic Name Report, Onym sends a one-time request to our Cloudflare-hosted naming proxy. The request contains the inputs needed to produce names — your Chinese name, region, gender preference, vibe tags, and (if provided) the Five-Elements summary derived locally from your birth date. We forward this to a large-language-model provider (currently DeepSeek), receive the generated names, and return them to your device.
The proxy does not log the request body, does not associate it with any identifier, and does not retain it after the response is returned. The upstream LLM provider may temporarily process the request under its own privacy terms; we send no email, no device identifier, and no persistent token alongside.
4. Birth date and the Five Elements
If you provide a birth date, Onym uses it locally to compute a Five-Elements (五行) personality summary, a cultural framework that shapes the naming guide's tone. This is a cultural personality analysis, not a destiny or fortune prediction. Onym makes no claims about your future, your finances, your health, your relationships, or any other life outcome. You can use Onym without ever providing a birth date.
5. Third-party services
Onym relies on these external services:
- Apple App Store / Google Play in-app purchases (via RevenueCat) — when you choose to unlock the full report. Receipts are handled by Apple or Google directly; we never see your payment details. RevenueCat receives an anonymous user identifier so it can verify your purchase across devices linked to the same store account.
- Cloudflare — hosts the LLM proxy described in Section 3 and this website. Cloudflare may log request metadata (IP address, user agent, timestamp) for security and abuse prevention purposes.
- DeepSeek (LLM provider) — receives the anonymized request body to generate names. Subject to DeepSeek's privacy policy.
- Sentry (crash diagnostics, opt-out by uninstalling) — receives anonymized crash reports when the app encounters an unexpected error. No naming inputs are included in crash payloads.
6. Your rights
Because we don't store your data, most data-subject rights apply directly to your device:
- Access — your naming history is fully visible in the History tab.
- Deletion — Settings → Delete all my local data wipes everything in a single tap.
- Portability — every paid report can be exported as PDF and shared anywhere.
For requests related to purchases, App Store / Play Store account data, or anything else Apple / Google holds on our behalf, please contact Apple or Google directly through their respective stores.
7. Children's privacy
Onym is not directed at children under 13. We do not knowingly collect data from anyone under 13. If you believe a child has used the app, please contact us and we'll help wipe any local data on that device.
8. Changes to this policy
If we change this policy, we will update the "Last updated" date at the top and, where the change is material, surface a one-time notice in the app on next launch.
