Privacy & Terms
Plain-English Summary: We only collect what's needed to run the service. We never ask for your private keys or seed phrases. Wallet addresses and transaction hashes are processed to classify transactions — we don't store them after your session unless you explicitly save results. Payments go through a secure payment processor; we never see your full card number.
1. Information We Collect
Crypto Tax Edge ("we," "us," or "our") collects the following categories of information when you use our website at cryptotaxedge.com and our web application at app.cryptotaxedge.com:
Account Information
When you create an account, we collect your email address, a hashed password or OAuth token (if you sign in via a third-party provider), and the date your account was created. We assign an internal user ID that is referenced throughout the service.
Transaction & Wallet Data
To classify transactions, you submit one or more of the following: transaction hashes, wallet addresses, or CSV files containing transaction records. This data is processed in real time to generate tax classifications. See Section 4 for full details on how this data is handled.
Usage & Technical Data
We automatically collect standard server log data when you visit or use the service, including IP address, browser type, operating system, referring URL, pages visited, and timestamps. This data is used for security, abuse prevention, and improving the service.
Communications
If you contact us by email or through a support channel, we retain the content of that communication and your contact details in order to respond and maintain a support history.
2. How We Use Your Information
We use the information we collect to:
- Provide, operate, and improve the Crypto Tax Edge platform and its classification tools
- Authenticate your account and maintain your session
- Process and fulfill subscription payments through our payment processor
- Send transactional emails such as account confirmation, password reset, and billing receipts
- Monitor for fraud, abuse, and unauthorized access
- Respond to support requests and inquiries
- Comply with applicable legal obligations
We do not sell your personal information to third parties. We do not use your data for advertising or share it with data brokers.
3. Third-Party Services & Data Processors
Crypto Tax Edge relies on third-party services to deliver its core functionality. Each service has access only to the data necessary to perform its specific function.
Blockchain Data Providers
We use third-party blockchain data providers to retrieve, parse, and cross-validate on-chain transaction activity. Only public blockchain data — such as transaction hashes and publicly visible on-chain records — is shared with these services. No personal information is transmitted to blockchain data providers.
AI Classification Engine
Transaction context and classification inputs are passed to a third-party AI service to generate tax classifications and reasoning. No personally identifiable account information is included in these requests. Data sent to our AI provider is governed by their respective data use policies.
Payment Processing
All payment processing is handled by a PCI-compliant third-party payment processor. We never receive or store your full credit card number or CVV.
Hosting & Authentication
Account data, authentication sessions, and saved user results are stored in a secure, hosted database. Data is processed in accordance with our hosting provider's privacy and security policies.
4. On-Chain & Wallet Data
We never ask for private keys, seed phrases, or wallet signatures. All blockchain data processed by Crypto Tax Edge is read from public sources only.
When you submit a transaction hash or wallet address, we query publicly available blockchain data through our data providers. This data is inherently public — it exists on-chain regardless of our service.
Transaction hashes and wallet addresses submitted for classification are processed ephemerally for users on the free tier. For paid subscribers, classification results may be cached and stored to avoid re-consuming your monthly quota when you re-run the same hash. You can delete saved results from your account dashboard at any time.
We do not link wallet addresses to your personal identity beyond what you choose to associate in your account. We do not cross-reference your wallet data with off-chain identity sources.
5. Payment Processing
Subscription payments are processed entirely by a PCI-compliant third-party payment processor. When you enter payment details, that information is transmitted directly to the processor's servers using TLS encryption. Crypto Tax Edge receives only a customer ID, subscription status, and the last four digits of your card for display purposes.
Billing records are retained for accounting and tax compliance purposes for a minimum of seven years, as required by applicable financial regulations.
6. Data Retention
We retain your account data for as long as your account remains active. If you delete your account, we will delete or anonymize your personal data within 30 days, except where retention is required by law (such as billing records).
Transaction classification results cached at your request are retained until you delete them or close your account. Server logs are retained for up to 90 days for security and debugging purposes.
7. Cookies & Analytics
We use essential cookies to maintain your authenticated session. We do not use third-party advertising cookies. If we deploy analytics tools, they will be configured to avoid collecting personally identifiable information, and this policy will be updated accordingly.
8. Your Rights
Depending on your jurisdiction, you may have the right to access, correct, export, or delete your personal data. To exercise any of these rights, contact us at hello@cryptotaxedge.com. We will respond within 30 days.
You may also delete your account at any time from your account settings, which will trigger deletion of your personal data as described in Section 6.
9. Chrome Extension — Data Collection, Handling, Storage & Sharing
The Crypto Tax Edge Chrome extension ("the Extension") processes user data in accordance with the Chrome Web Store User Data Policy, including the Limited Use requirements. This section describes, explicitly and in full, what data the Extension collects, handles, stores, and shares.
Data Collection
The Extension collects only the data required to provide its classification feature:
- Transaction hashes you submit — either pasted into the Extension popup or detected on a supported tax platform page you visit.
- Account credentials — if you sign in, your email address and a session token are stored locally in your browser so you remain signed in.
- Google Identity data — if you sign in via Google, the Extension uses the Chrome Identity API to obtain your Google email address and a session token. No other Google account data (contacts, calendar, Drive files, etc.) is accessed or collected. The Google email is used solely for authentication and is handled identically to a manually entered email address.
- Anonymous usage telemetry — which classification path was taken and how long it took. This contains no personal information and no transaction content.
- Subscription state — your tier and monthly usage counter, so the Extension can enforce free-tier limits.
The Extension does not collect: browsing history, page content outside supported tax platform domains, form inputs unrelated to classification, keystrokes, or any other browser activity.
The Extension never asks for, collects, or transmits private keys, seed phrases, mnemonic phrases, wallet signatures, or any cryptographic secrets.
Why the Extension Requires Host Permissions
The Extension declares host permissions for specific cryptocurrency tax platform domains (such as Koinly, CoinTracker, TaxBit, and others listed in the Extension's manifest). These permissions are required so the Extension can:
- Detect transaction hashes displayed on pages within these supported platforms
- Inject an in-page classification overlay showing tax analysis results directly alongside your transaction data
- Communicate with our backend API at app.cryptotaxedge.com to retrieve classification results
The Extension only activates on the specific tax platform domains listed in its manifest. It does not run on, read data from, or interact with any other websites. Content scripts are injected solely to provide the classification overlay feature — no page content is scraped, stored, or transmitted beyond the transaction hashes visible on the page.
Data Handling
All data handled by the Extension is processed exclusively to provide the classification feature the user requested:
- Transaction hashes are transmitted over HTTPS to our backend for classification.
- Session tokens are used solely to identify the signed-in user and enforce tier limits.
- Classification results are returned to the Extension and displayed in the popup or as an in-page overlay.
- No data handled by the Extension is used for advertising, sold, used to build user profiles, used for credit assessment, or used for any purpose unrelated to classification.
Data Storage
Data is stored in the following locations only:
- Locally in your browser (via Chrome Storage API): session tokens, cached configuration, preferences, and a short-lived cache of recent classifications. This local data never leaves your browser except when you initiate a classification request.
- In our hosted database (Supabase, hosted on AWS): your account record (email, hashed credentials, account creation date, tier, usage counter) and, for paid subscribers, cached classification results keyed by transaction hash.
Account data is retained while your account is active. If you uninstall the Extension, local data is removed by your browser. If you delete your account, associated data is deleted or anonymized within 30 days as described in Section 6.
Data Sharing
We share data only with the categories of third-party service providers described in Section 3, and only to the extent necessary to deliver the classification feature:
- Blockchain data providers receive only transaction hashes and public on-chain addresses.
- Our AI classification engine receives decoded transaction data and protocol context. No personal account information is included.
- Our hosting and authentication provider stores account data and sessions.
- Our payment processor handles subscription billing. The Extension itself does not transmit payment data.
We do not sell, rent, trade, or transfer user data to data brokers, advertising networks, or marketing companies. Data shared with service providers is used exclusively to deliver the functionality the user requested.
Data Security
We implement the following measures to protect data collected and processed by the Extension:
- Encryption in transit — all communication between the Extension and our backend uses HTTPS (TLS 1.2+). No data is transmitted over unencrypted connections.
- Encryption at rest — account data and cached classification results stored in our hosted database are encrypted at rest using AES-256 encryption provided by our infrastructure provider.
- Authentication security — passwords are hashed using bcrypt before storage. Session tokens are cryptographically signed and expire automatically.
- Minimal data collection — we collect only the data strictly necessary to provide the classification feature, reducing the surface area for potential data exposure.
- Access controls — access to production databases is restricted to authorized personnel using role-based access controls and multi-factor authentication.
Consent and Control
By installing the Extension, you consent to the data practices described in this section. You can revoke consent at any time by uninstalling the Extension or deleting your account. Contact hello@cryptotaxedge.com to request access, correction, export, or deletion of any data associated with your account.
10. Children's Privacy
Crypto Tax Edge is not directed at individuals under the age of 18. We do not knowingly collect personal information from minors. If you believe a minor has provided us with personal information, please contact us and we will delete it promptly.
11. Changes to This Policy
We may update this Privacy Policy from time to time. When we do, we will revise the "Last updated" date at the top of this page. For material changes, we will notify you by email or via an in-app notice. Continued use of the service after changes take effect constitutes acceptance of the updated policy.

Plain-English Summary: Crypto Tax Edge is a classification tool — not a licensed tax advisor. The outputs it generates are informational only. You are responsible for verifying results and consulting a qualified tax professional before filing. Use the service lawfully and don't attempt to abuse or reverse-engineer it.
1. Acceptance of Terms
By accessing or using Crypto Tax Edge (the "Service") — including the website at cryptotaxedge.com and the application at app.cryptotaxedge.com — you agree to be bound by these Terms of Service ("Terms"). If you do not agree, do not use the Service.
These Terms apply to all users, including free-tier users, paid subscribers, and visitors to the marketing site.
2. Description of Service
Crypto Tax Edge provides AI-assisted classification of cryptocurrency transactions for informational and tax preparation purposes. The Service uses a multi-source analysis engine combining blockchain data providers and AI classification to identify transaction types, assign tax-relevant categories, and generate exports compatible with third-party tax software such as Koinly.
The Service is provided on an "as-is" basis and is subject to change. Features may be added, modified, or removed at any time.
3. Not Tax or Legal Advice
Important: Crypto Tax Edge is a software tool, not a licensed tax advisor, CPA, attorney, or financial advisor. Nothing produced by the Service constitutes tax advice, legal advice, or a guarantee of tax compliance.
Transaction classifications, tax category assignments, confidence scores, and any other outputs generated by the Service are provided for informational purposes only. They are based on publicly available blockchain data and AI inference — they may be incomplete, incorrect, or inapplicable to your specific tax situation.
You are solely responsible for:
- Verifying the accuracy of all classifications before use in tax filings
- Consulting a qualified tax professional or CPA regarding your specific obligations
- Ensuring your tax filings comply with applicable law
- Any penalties, interest, or liabilities arising from your tax filings
Crypto Tax Edge makes no representations regarding the tax treatment of any specific transaction under current or future law.
4. Accounts & Eligibility
To access paid features, you must create an account. You agree to provide accurate, current, and complete information during registration and to keep your account information updated.
You must be at least 18 years of age to create an account. By creating an account, you represent that you meet this requirement.
You are responsible for maintaining the confidentiality of your credentials and for all activity that occurs under your account. Notify us immediately at hello@cryptotaxedge.com if you suspect unauthorized access.
5. Subscription Plans & Billing
Plans
Crypto Tax Edge offers free and paid subscription tiers. Paid plans are billed monthly or annually as selected at checkout. Current plan details and pricing are described at cryptotaxedge.com/#pricing and are subject to change with notice.
Free Trial
Paid plans may include a free trial period. If a trial is offered, you will not be charged until the trial period ends. You may cancel before the trial ends to avoid any charge. After the trial, your subscription will automatically convert to a paid plan at the stated rate.
Billing & Renewal
Subscriptions renew automatically at the end of each billing period unless cancelled. All payments are processed by a PCI-compliant payment processor. By providing payment information, you authorize Crypto Tax Edge to charge your payment method for the applicable subscription fees.
Cancellation & Refunds
You may cancel your subscription at any time from your account settings. Cancellation takes effect at the end of the current billing period — you retain access through that date. We do not offer prorated refunds for partial billing periods. If you believe you have been charged in error, contact us within 30 days of the charge.
Usage Limits
Each plan includes a defined number of hash classifications per month. Usage resets on your billing date. Unused classifications do not roll over. Exceeding your plan's limit will require an upgrade to continue classifying transactions for that period.
6. Acceptable Use

Violation of these terms may result in immediate account suspension or termination.
7. Intellectual Property
All content, software, design, trademarks, and other intellectual property associated with the Service are owned by or licensed to Crypto Tax Edge. You are granted a limited, non-exclusive, non-transferable license to use the Service for its intended purpose during your subscription term.
You retain ownership of any data you submit to the Service. By submitting such data, you grant us a limited license to process it solely for the purpose of delivering the Service to you.
Classification outputs generated by the Service may be downloaded and used for personal tax preparation. You may not resell, redistribute, or commercially exploit Service outputs without our written consent.
8. Third-Party Services
The Service integrates with third-party providers for blockchain data, AI classification, payment processing, and hosting. Your use of the Service is also subject to the terms of these providers where applicable. We are not responsible for the actions, availability, or accuracy of third-party services.
9. Disclaimers & Limitation of Liability
The Service is provided "as is" and "as available" without warranties of any kind, express or implied. We disclaim all warranties including implied warranties of merchantability, fitness for a particular purpose, accuracy, and non-infringement.
We do not warrant that transaction classifications will be accurate or suitable for any specific tax filing, that the Service will be uninterrupted or error-free, or that third-party data providers will return accurate results.
To the maximum extent permitted by applicable law, Crypto Tax Edge's total liability for any claim arising out of or relating to these Terms or the Service shall not exceed the greater of (a) the amount you paid us in the 12 months preceding the claim, or (b) $100 USD.
In no event shall Crypto Tax Edge be liable for any indirect, incidental, special, consequential, or punitive damages — including tax penalties, audit costs, lost profits, or data loss — even if advised of the possibility of such damages.
10. Indemnification
You agree to indemnify, defend, and hold harmless Crypto Tax Edge and its officers, employees, and agents from any claims, damages, liabilities, costs, and expenses (including reasonable legal fees) arising from: (a) your use of the Service; (b) your violation of these Terms; (c) your violation of any third-party rights; or (d) any tax filings or financial decisions made based on Service outputs.
11. Termination
We reserve the right to suspend or terminate your account at our discretion, with or without notice, for conduct that violates these Terms or that we determine is harmful to the Service, other users, or third parties.
You may terminate your account at any time from your account settings. Upon termination, your right to use the Service ceases immediately. Provisions that by their nature should survive termination — including Sections 3, 7, 9, 10, and 12 — will survive.
12. Governing Law & Disputes
These Terms are governed by and construed in accordance with applicable law, without regard to conflict-of-law principles. Any dispute arising out of or relating to these Terms or the Service that cannot be resolved informally shall be resolved through binding individual arbitration — not as a class action.
Before initiating arbitration, you agree to contact us at hello@cryptotaxedge.com and attempt to resolve the dispute informally for at least 30 days.
13. Changes to Terms
We may revise these Terms at any time. When we make material changes, we will update the "Last updated" date and notify you by email or in-app notice. Continued use of the Service after updated Terms take effect constitutes your acceptance.
