Privacy Policy
Version 1
The Korean version is the governing text.
nexonbook Corp. (the "Company") processes personal data as follows.
1. Data We Process
Account data (email, hashed password) for sign-in and notices, kept until account deletion; uploaded documents and converted DOX to provide the service, deleted when you delete them or your account; credit transaction records for billing and fraud prevention, kept 5 years as required by Korean e-commerce law; access logs and essential cookies for security, kept 3 months. We do not store card details — payments are handled by Paddle as Merchant of Record. The Service is not for children under 14.
2. Processors and International Transfers — Important
| Processor | Country | Data | Purpose |
|---|---|---|---|
| Amazon Web Services | Korea (Seoul region) | Stored service data | Hosting and storage |
| Amazon Web Services (SES) | USA (Oregon) | Email address, message | Verification and notice emails |
| Paddle.com Market Ltd. | UK and others | Payment data (collected directly by Paddle) | Payment, tax, refunds (as independent Merchant of Record) |
| Google LLC | USA | Content of documents for which you run translation or Precision Review (text; Precision Review also sends page images of the original) | Machine translation and review against the original (AI model calls) — not used for model training |
| Anthropic, PBC | USA | Only if the second pass of Precision Review is enabled, the content (text and images) of pages flagged by the first pass | Re-checking Precision Review findings (AI model calls) — not used for model training |
| Mathpix, Inc. | USA | The entire uploaded PDF (its text and images) | Document recognition (OCR) and structure extraction — source files are not stored (we opt out of data use for model improvement); processing outputs are auto-deleted by the processor within 90 days |
Every uploaded PDF is transferred to Mathpix without exception. The conversion of DOCX files happens on our own servers and is not transferred externally. The transfers above happen only when you run translation or Precision Review. Precision Review renders page images of the original and sends them as well; those images are kept in our storage for a limited period so you can view the result again, and are then deleted automatically. You may refuse international transfers, in which case the corresponding features (PDF conversion, translation, Precision Review, payments) will be unavailable. Display settings and offline-viewer bookmarks are stored only in your browser (localStorage), not on our servers.
3. Deletion, Your Rights, Security, Cookies, Contact
Data is irreversibly deleted when retention ends. You may request access, correction, deletion, or restriction at any time (privacy@palmdox.com). We use TLS in transit, one-way password hashing, least-privilege access, and access logging. Only essential cookies are used; no advertising cookies. Changes to this policy are announced 7 days in advance (30 days for material changes).
Effective date: [ ]
