Privacy Policy
Last updated: July 8, 2026 · Effective date: July 8, 2026
The full text below is in English, the legally authoritative version.
KAERIS i18n (kaeris.dev) is operated by Vyacheslav Kojima, an individual entrepreneur based in Ukraine. This policy explains what data we collect, why, and your rights over it. We keep things simple because we collect very little.
1. What data we collect and why
| Data | Why | Stored where | Retention |
|---|---|---|---|
| IP address | Rate limiting (abuse prevention) | In-memory only, not written to disk | Until server restart |
| Uploaded file content | AI translation (sent to OpenRouter) | Temp files on server, deleted within 2 hours | Max 2 hours |
| Email address | Sending your API key after purchase | orders.json on server | Until deletion request |
| API key | Authentication | api_keys.txt / premium_keys.txt on server | Until you request removal |
| Chat messages | AI support responses (sent to OpenRouter) | Not stored — processed in real time | Not retained |
| Language preference | UI language memory | Your browser's localStorage only | Until you clear browser data |
| Payment data | Processing purchases | Handled by Creem — we never see card details | Creem's policy applies |
We use no cookies. We use browser localStorage only for your language preference — no tracking, no analytics, no advertising.
2. Third-party sub-processors
To deliver the service we share data with these providers:
| Provider | Purpose | Data shared | Privacy policy |
|---|---|---|---|
| OpenRouter | AI translation & chat (routes to DeepSeek / OpenAI) | File content, chat messages | openrouter.ai/privacy |
| DeepSeek | AI model (free tier) | File content (via OpenRouter) | deepseek.com/privacy |
| OpenAI | AI model (Pro/Lifetime — GPT-4o-mini) | File content (via OpenRouter) | openai.com/policies |
| Creem | Payment processing | Email, order metadata | creem.io/privacy |
| Cloudflare | CDN, DDoS protection, DNS | IP address, HTTP headers | cloudflare.com/privacypolicy |
| Google Fonts | Onest, Unbounded & JetBrains Mono typefaces | IP address (CSS request) | policies.google.com/privacy |
Important: When you upload a file, its content is sent to OpenRouter for AI translation. Do not upload files containing personal data, passwords, or confidential information not related to UI strings.
3. Legal basis for processing (GDPR)
For users in the European Economic Area, our legal basis is:
- Contract performance — processing your translation request, delivering your API key after purchase
- Legitimate interest — IP-based rate limiting to prevent abuse
- Legal obligation — retaining order records as required by applicable law
4. Your rights
You have the right to:
- Access — request a copy of data we hold about you
- Erasure — request deletion of your email and API key from our records
- Rectification — correct inaccurate data
- Portability — receive your data in a structured format
- Object — object to processing based on legitimate interest
- Withdraw consent — where processing is based on consent
To exercise any right, email [email protected]. We respond within 30 days. Deletion requests are honored within 7 days for email and API keys.
5. Data retention
- Uploaded files — deleted from our server within 2 hours of the translation job completing
- Email & order record — retained until you request deletion, or 3 years from last purchase (whichever is sooner), for accounting purposes
- API keys — retained until you request removal; your key stops working immediately upon deletion
- IP addresses — never written to disk; lost on server restart
6. Security
We use HTTPS everywhere (TLS 1.2+, enforced by Cloudflare). Data files on our server are permission-restricted. We do not store payment card data — Creem handles all payment processing under PCI-DSS compliance.
7. Children
KAERIS i18n is not directed at children under 13 (under 16 in the EU). We do not knowingly collect personal data from children. If you believe a child has submitted data, contact us and we will delete it promptly.
8. International transfers
Your file content may be processed by OpenRouter/DeepSeek/OpenAI servers located in the United States. These transfers are covered by standard contractual clauses or the providers' own adequacy frameworks. By using the service you acknowledge this transfer.
9. California (CCPA)
We do not sell personal information. We do not share personal information for cross-context behavioral advertising. California residents have the right to know, delete, and opt out of sale — contact us at [email protected].
10. Changes to this policy
We may update this policy. When we do, we update the "Last updated" date at the top. Continued use after changes constitutes acceptance. Material changes will be announced on kaeris.dev.
