Clean Viewer Terms of Use

Effective: November 2, 2026 · Last updated: November 12, 2026 (Article 3 item 2 adds Fix text · new item 4) · The Korean version (/terms) prevails.

In short: a free document viewer with no sign-up and no ads. Files you open are handled on your device (or in your browser) and never sent to us.

Article 1 (Purpose)

These terms set the conditions for using the "Clean Viewer" app and website (the "service") provided by Sequencen Inc. (the "company").

Article 2 (The service)

  1. The service opens files you choose (PDF, Hangul, Word, Excel, PowerPoint, photos and more) on your device and offers marking, signing, scanning and saving as PDF.
  2. The service is free, needs no sign-up or login, and shows no ads.
  3. Files are processed on your device and are never sent to or stored on company servers. See the Privacy Policy.

Article 3 (Your responsibilities)

  1. Open only files you have the right to view or edit.
  2. You are responsible for documents you create with signatures, stamps, redaction or Fix text and for how you use them.
  3. "Find and redact personal info" only points out what it finds; check the result before submitting a document.
  4. Do not use Fix text to alter someone else's document, or an official document or certificate, in order to deceive. A fixed copy keeps one line noting that it was fixed and the date.

Article 4 (Changes and interruptions)

We may change, add or remove features. Important changes that work against you are announced in the app and on the website 7 days in advance. The web service may pause briefly for maintenance or outages.

Article 5 (Limits of liability)

  1. The service does not guarantee that every file looks exactly as in its original program. Check important documents in the original program too.
  2. For this free service, the company is not liable for your losses unless caused by its intent or gross negligence, except where the law provides otherwise.
  3. Files and records you delete on your device (such as recent documents) are not kept by the company and cannot be restored.

Article 6 (Intellectual property)

Rights to the service's software, design and marks belong to the company. Included open-source software follows its licenses listed in the open-source notices. Rights to the files you open belong to you or their authors.

Article 7 (Disputes and governing law)

Questions and complaints go to support (+82 1566-3020 · ceo@sequencen.com) and are answered without delay. These terms are governed by the laws of the Republic of Korea, and the competent court is determined under the Korean Civil Procedure Act.
