Privacy Policy
NurViewer is a local-first file viewer, reader, conversion, recognition, and study application published by NURSOVA LLC ("NURSOVA", "we", "us"). This policy explains the information processed by the NurViewer Windows product and its account, licensing, and purchase services.
1. Local document processing
NurViewer is designed so that ordinary viewing, local search/indexing, OCR, conversion, annotation, media study, and similar file-processing workflows operate on the user's device. The NurViewer authentication and licensing service does not require document contents, filenames, local file paths, OCR text, thumbnails, annotation contents, media contents, or the local full-text index in order to provide account or licence services.
Opening a file in NurViewer is not, by itself, an upload of that file to NURSOVA. A format, operating-system component, external link, or third-party service explicitly chosen by the user may have its own behavior and terms.
2. Information we process
Account and sign-in information
If you sign in with Google or Microsoft, we process the provider identity needed to create and secure your NurViewer account. Depending on what the provider supplies, this can include a provider-specific subject identifier, email address, email-verification state, and display name. We do not receive or store your Google or Microsoft account password.
Session and security information
Our service processes session identifiers, hashed access/refresh-token values, login outcome and timestamps, and privacy-reduced network/security signals such as hashed IP-address and user-agent values. These records are used to authenticate requests, rotate sessions, investigate abuse, and protect accounts and licences.
Device, licence, and quota information
NurViewer may process a pseudonymous installation hash, platform, optional device label, app version, licence/plan status, device activation state, last-seen times, and feature quota counters. Quota records can include a pseudonymous resource key used to prevent duplicate counting; they are not intended to contain the source filename or local path.
Purchase and entitlement information
When you purchase a paid NurViewer plan through the Nursova website and an external payment provider, we process the account and entitlement information needed to determine your NurViewer plan, such as provider/customer/transaction identifiers, plan or price identifiers, entitlement status, purchase time, and refund/revocation state. Payment-card details are handled by the payment provider and are not required by the NurViewer authentication/licensing service.
Diagnostics and support
NurViewer creates privacy-reduced local diagnostic breadcrumbs with stable support references such as NV-.... These diagnostics are stored locally and are not automatically uploaded to NURSOVA. If you choose to send diagnostic information to support, we process what you voluntarily provide for troubleshooting.
3. What we do not use your files for
- We do not sell your private document contents.
- We do not use your private document contents for behavioral advertising.
- We do not require document contents to train a NURSOVA generative model as part of the current NurViewer account/licensing service.
- We do not ask you to email passwords, OAuth tokens, payment-provider API/webhook secrets, licence tokens, or signing keys for support.
4. Why we process information
We process the information above to provide sign-in and account security, validate purchases and licences, enforce registered-device and online-concurrency limits, apply plan quotas, restore entitlements, prevent duplicate billing/usage operations, investigate service abuse, and provide requested support.
5. Service providers and disclosures
NurViewer uses service providers where necessary to operate the product. Current first-release dependencies include Cloudflare for the NurViewer authentication/licensing service and database, Google and Microsoft for optional sign-in, Microsoft Store for Windows distribution/updates, and the external payment provider Paddle for paid checkout. Those providers may process information under their own terms and privacy policies.
We may also disclose information when reasonably necessary to comply with law, protect users or the service, investigate fraud or abuse, or complete a corporate transaction subject to appropriate protections.
6. Retention
We retain account, licence, transaction, security, and operational records for as long as reasonably necessary to provide the product, maintain licence and purchase history, secure accounts, resolve disputes, comply with legal obligations, and prevent fraud. Different record types can have different retention periods. Expiration of a session or licence does not necessarily mean the corresponding historical record is deleted immediately.
7. Your choices and requests
You can stop using NurViewer without uploading your local files to NURSOVA. For questions, correction requests, or account/privacy requests, contact legal@nursova.com or support@nursova.com. We may need to verify the requester before acting on an account-related request. Some transaction, fraud-prevention, tax, security, or legal records may need to be retained even after an account request.
8. Security
We use measures intended to reduce unnecessary exposure of authentication and licensing data, including hashed bearer-token storage, signed licence leases, scoped device identifiers, secret storage outside the distributed app, and privacy-reduced diagnostics. No system can guarantee absolute security, and users remain responsible for the security of their device and third-party accounts.
9. Children
NurViewer is a general-purpose productivity application and is not directed to children under 13. If you believe a child has provided personal information to us in circumstances requiring deletion, contact us using the details below.
10. Changes to this policy
We may update this policy when the product, law, or service providers change. The effective date and policy-version marker at the top identify the version published for the current product. Material changes will be reflected on the public NurViewer policy page before or when they take effect as appropriate.
