Summary: We collect only what we need to run the service. We do not sell your data, and we do not use advertising or third-party tracking. You can request deletion of your data at any time.
Greeks ("we", "us", "our") operates the options analytics platform at greeks.pro. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our Service.
| Data | When collected | Why |
|---|---|---|
| Email address | Registration | Account identification, transactional emails |
| Password (hashed) | Registration | Authentication — never stored in plain text |
| API keys | Generated on registration | Service authentication |
| Usage data | Each API request | Rate limiting, quota enforcement, analytics |
| Payment data | Subscription checkout | Billing — handled by a PCI-compliant payment processor, never stored by us |
| IP address | Each request | Security, abuse prevention |
| Browser/device info | Web sessions | Service optimization |
We do not collect your trading activity, portfolio data, brokerage account information, or any financial data beyond what is necessary to operate the Service.
We do not use your data for advertising, profiling, or sale to third parties.
We share your data only with the trusted service providers that make the Service work, and only to the extent necessary to operate it:
These providers are contractually bound to protect your data and may only use it to provide their service to us. We do not sell, rent, or share your personal data with any other third parties for marketing or commercial purposes.
We do not use advertising cookies, third-party analytics scripts (e.g., Google Analytics), tracking pixels, or cross-site retargeting. We use only first-party cookies and local storage, entirely under our own control, for the purposes below.
| Name | Type | Purpose | Expires |
|---|---|---|---|
| grk_consent | First-party cookie | Remembers your choice to accept or decline product analytics, so we don't ask again | 1 year |
| grk_vid | First-party cookie | A random, anonymous visitor ID used only to measure product usage (pages viewed, sign-up funnel). Set only after you accept. Not a fingerprint and never linked to advertising. | 1 year |
| apiKey, plan, email, userId | Browser localStorage | Keeps you logged in and remembers your plan. Stays on your device; never sent to third parties. | Until logout |
Consent: When you first visit, we ask before setting the analytics cookie (grk_vid). If you decline, no analytics cookie is set and no usage events are recorded. Essential storage that keeps you logged in (localStorage above) is required for the Service to function and is not used for tracking.
Our product analytics are first-party: usage data is collected and stored by us, is not sold or shared, records no raw IP address (only a coarse network prefix for security), and is automatically deleted after 180 days.
You have the right to:
To exercise any of these rights, email support@greeks.pro. We will respond within 30 days.
We implement industry-standard security measures including:
No method of transmission over the internet is 100% secure. We cannot guarantee absolute security, but we commit to notifying affected users promptly in the event of a data breach.
The Service is not directed to individuals under the age of 18. We do not knowingly collect personal information from minors. If you believe we have inadvertently collected such data, contact us immediately.
We may update this Privacy Policy periodically. We will notify you of material changes by posting the new policy on this page and updating the "Last updated" date. For significant changes, we will also send an email notification to registered users.
