Terms of Service

Last updated: 2026-11-04

By using PcapDecoder ("the App") or creating an account, you agree to these terms.

1. The service

The App is a network packet capture and traffic analysis tool: it opens PCAP/PCAPNG files or ingests live captures, and provides protocol dissection, conversation analysis, expert diagnostics, threat detection, optional AI assistance and report export. The core analysis engine runs entirely on your device; the account, cloud AI and cross-device sync are optional features.

2. Account

• Provide accurate information and keep your credentials secure. You are responsible for activity under your account.
• Local analysis works without sign-in. An account is needed only for hosted cloud-AI quotas, subscriptions and purchase restore across devices.
• You may delete your account any time via Settings → Account → Delete Account, as described in the Privacy Policy.

3. Lawful authorization (important)

• Use the App only to capture and analyze traffic you own or are explicitly authorized to analyze: your own devices, networks you own, or captures obtained with lawful permission.
• Do not use the App or its capture features to intercept or monitor communications without authorization. Capturing other people's traffic is regulated (and in many jurisdictions criminal) under local law. Get proper authorization before capturing on corporate, public or third-party networks.
• You are responsible for consequences of capturing or analyzing beyond your rights.

4. Your content

• You keep all rights to capture files, reports and content you create. We do not store your capture files — they remain on your device.
• When you export or share reports, ensure the content is authorized for sharing. Captures may contain sensitive material (credentials, cookies, personal data); the App offers redaction aids, but the judgment to share is yours.

5. AI features

• AI explanations (cloud AI or BYOK) are assistive: conclusions about faults, threats or compliance may be inaccurate or incomplete and do not constitute professional network-engineering, security or legal advice. Always verify critical remediation decisions against the raw packets.
• Do not submit network content via AI features that you have no right to access.
• Cloud AI is subject to a daily quota (see the in-app counter and Help & Support). Failed cloud calls do not consume quota.

6. Membership and purchases

• Paid features are offered through in-app purchases on the Apple App Store and Google Play:
  • PRO Lifetime — a one-time purchase with long-lived extended local capabilities and BYOK direct AI; it does not include hosted cloud AI.
  • PRO subscription (monthly / yearly) — the PRO benefit track; hosted cloud AI remains on the free daily quota.
  • PRO+ subscription (monthly / yearly) — adds a hosted cloud-AI daily quota (currently 100/day; in-app display governs).
  • Lifetime and subscription benefits are two tracks: when a subscription lapses, you keep everything you purchased outright; lifetime purchases are never affected.
• Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel any time in your Apple ID / Google Play subscription settings.
• Restore Purchases: on a new device or after reinstall, tap "Restore Purchases" on the paywall.
• All purchases are billed by the store; prices are displayed in the App at the time of purchase. Refunds are handled by the store under its policies. On Apple devices, Apple's Standard Licensed Application End User License Agreement applies alongside these terms.
• Desktop editions (Windows / macOS) do not offer in-App purchase; buy on mobile and sign in with the same account to use your entitlements.

7. Acceptable use

Do not: intrude upon or disrupt the service; attempt to access other users' data; circumvent AI quotas or entitlement limits; resell accounts; or use the App unlawfully. We may suspend accounts that harm the service or others.

8. Availability and changes

We aim for good availability but do not guarantee uninterrupted service. Features may be updated or adjusted; some capabilities may roll out per platform first. Material changes to these terms will be announced in the App, and continued use after that means acceptance.

9. Disclaimer and liability

To the extent permitted by law, the App is provided "as is" without warranties of merchantability, fitness for a particular purpose or non-infringement, and we are not liable for indirect or consequential damages arising from reliance on analysis results or AI conclusions (including business interruption, data loss or network remediation costs). Nothing in these terms limits liability that cannot be limited under mandatory law.
