1. What we do not collect or transmit
NitroGPT does not transmit or store your ChatGPT conversation content on NitroGPT servers. Optimization happens locally in your browser.
- Your ChatGPT prompts or responses are not sent to NitroGPT servers
- Your ChatGPT account information is not collected by NitroGPT
- Your browsing history outside of chatgpt.com is not collected by NitroGPT
Hidden messages are stored in your browser's memory (not on any server) and are cleared when you close or reload the page.
2. Extension data
Trial data
When you install NitroGPT, the extension generates a random installation ID and contacts the NitroGPT server to start your 7-day Pro trial. The server stores:
- A hash of the installation ID
- A random local bootstrap token used to safely retry initial trial setup (stored as a hash on the server and as a token in your browser's local extension storage)
- A trial token (also stored in your browser's local extension storage)
- An installation token used to authenticate trial and Free-plan requests (stored as a hash on the server and as a token in your browser's local extension storage)
- A hashed IP address or IP prefix (for abuse detection)
- A hashed user-agent string (for abuse detection)
- A hashed, coarse trial bucket derived from IP prefix and broad browser or operating-system information (for trial abuse prevention)
- A server-controlled hashed Free-plan quota subject, which may be shared by closely matching anonymous installations to limit simple quota resets
- Browser family, browser name, and NitroGPT extension version
- A support code shown in the extension popup, used to help support review trial issues without needing your ChatGPT content
- Abuse-prevention status fields, such as abuse score, reason, and any support-granted trial override expiry
- The trial start and expiry timestamps
These trial-abuse-prevention fields are used to limit repeated free trials across browsers or installations and to help support resolve false positives. They are not used to collect, transmit, or analyze your ChatGPT conversations.
No personal data, email, or account is required to start the trial. Trial records are retained for 12 months after trial expiration, then deleted or anonymized.
License data
If you purchase NitroGPT Pro and activate a license, the server stores:
- Your license key (hashed)
- A hashed installation ID per activated browser
- An activation token issued to your browser (stored as a hash on the server)
- Browser family (Chrome/Chromium or Firefox)
- Browser name and NitroGPT extension version
- Activation and deactivation timestamps
Your purchase email is associated with your license in the Account Management Portal system for ownership verification. It is not used for marketing without your consent.
Free daily prompt count
On the Free plan, NitroGPT counts optimized prompts per day (maximum 30). The server stores a daily count against a server-controlled hashed quota subject. Closely matching anonymous installations may share that quota subject as an abuse-prevention measure. No prompt content, conversation content, or message text is sent. Records are retained for 90 days, then deleted or anonymized.
Settings
NitroGPT settings (visible messages count, toggles, etc.) are stored in your browser's local extension storage only. They are not sent to NitroGPT servers.
3. Website data (nitrogpt.app)
Essential storage
The NitroGPT website uses localStorage to remember your consent preference for analytics. This is strictly necessary for site functionality and is used without consent.
Optional analytics (with consent)
If you accept optional analytics, we generate a random anonymous session ID stored in your browser's sessionStorage. We use this to track basic conversion events (page views, pricing interest, install button clicks). No personal data is attached. No third-party analytics providers (Google Analytics, Facebook, etc.) are used.
Waitlist
If you join the waitlist, we collect your email address and the text of the consent you provided (including consent version and timestamp). We use this email only to notify you of the NitroGPT launch and, if applicable, relevant product updates. You can unsubscribe at any time. Waitlist records are retained while you remain subscribed or until the launch notification purpose is fulfilled.
4. Purchase and account data
Purchase transactions are processed through the N8 Solutions Account Management Portal. Customer account data — including name, email, billing address, and transaction records — is stored within N8 Solutions' existing account management system. This data is subject to N8 Solutions' standard data handling practices and applicable legal, accounting, and tax obligations.
5. Data retention
- Trial records: 12 months after trial expiration, including hashed or coarse abuse-prevention metadata and support override records, then deleted or anonymized.
- Free daily prompt count records: 90 days detailed, then deleted or aggregated.
- Waitlist records: While opted in, until launch notification purpose is complete.
- License and activation records: Retained as part of your account history while the account or license exists, and as required by law, accounting obligations, or dispute resolution needs thereafter.
- Paid customer account records: Retained per applicable accounting, tax, legal, anti-fraud, and contractual obligations.
6. Your rights
Depending on your jurisdiction, you may have the right to access, correct, or delete personal data we hold about you. You may also have the right to data portability, the right to object to processing, and the right to withdraw consent.
To exercise these rights, contact us at contact@nitrogpt.app or through the Account Management Portal if you are a paid customer.
7. Cookies and local storage
The NitroGPT website does not use tracking cookies. It uses localStorage for consent state and sessionStorage for optional anonymous analytics session IDs (with consent). The NitroGPT extension uses Chrome/Firefox extension local storage for settings, trial state, support code, and license cache. This data stays on your device.
