Security of Nani Translate
Nani Translate is developed and operated by Kioku LLC. Protecting your data is a top priority. We continuously review and improve security across design, development, and operations.
Data handling
Translation data (input and output) is not saved to our persistent storage (such as databases). We record usage metrics (token and character counts, etc.) and minimal information for abuse prevention (such as IP addresses for anonymous usage).
Translation history is stored only on your device (browser local storage or the desktop app’s local database).
Even on the Team plan, translation history is not shared between members and is stored independently on each device.
We do not store translation data, and our staff does not view your input or output.
Together, these measures make Nani Translate a reliable choice for business translation tasks, such as handling support inquiries and customer communication.
Network and infrastructure security
All communications are encrypted with HTTPS (TLS 1.2 or later).
User data we store is encrypted at rest in databases and backups.
If you use Nani behind a VPN, proxy, EDR, or URL filtering system, review the network allowlist for IT administrators.
View network allowlistOperational security
We continuously scan and monitor the software components we use (such as libraries). If a vulnerability could affect the service, we prioritize updates and fixes.
We use a managed web application firewall (WAF) on key public endpoints to block common attacks and malicious traffic.
Internal system access follows the principle of least privilege and is granted and reviewed based on business need.
AI providers and data transmission
To provide translation, proofreading, and other features, we send the necessary content to external AI services. We mainly use models developed by OpenAI and Google. For some purposes, we also use other services, but only those that explicitly state that your input and output are not used for training and are not retained after processing.
On all plans, including Free, neither Nani nor its AI providers use your input or output for model training. We also do not use it to improve our service.
OpenAI and Google may temporarily store your input and output for safety purposes, but they do not use them to train AI models.
Authentication and access control
User authentication uses Google OAuth 2.0, and our servers never store passwords.
Payment security
Payments are processed by Stripe, a PCI DSS Service Provider Level 1 certified provider. Card details are tokenized by Stripe and do not pass through our servers. Payment details (such as card numbers) are never stored on our servers.
Account and data deletion
Users can delete their accounts at any time. We generally delete user data on our servers, but may retain some data for a limited period for security purposes and fraud prevention.
