3. SMS & Email Weather Alerts (PRO Feature)
VectorWX PRO subscribers may opt in to receive weather alert notifications via SMS text messages and/or email. By opting in, you agree to the following:
- Opt-In: Weather alert SMS and email notifications are strictly opt-in. You will never receive SMS or marketing emails without your explicit consent.
- Message types: Severe weather alerts (tornado, severe thunderstorm, flash flood warnings), lightning proximity alerts, and custom threshold alerts you configure.

- SMS rates: Standard message and data rates may apply. VectorWX does not charge for SMS delivery, but your carrier may.
- Phone number: Your phone number is stored securely and used exclusively for delivering weather alerts you have subscribed to. It is never shared with third parties for marketing purposes.
4. Data Sharing & Third Parties
We share your information only in these limited circumstances:
- Stripe: Payment processing (email, name for billing)
- SMS provider: Phone number for alert delivery (PRO opt-in only)
- Cloudflare Email Service: Email delivery for account notifications and alert emails
- Google Ads: Conversion measurement for our ads (sign-ups and upgrades), subject to your cookie choice (see Section 6)
- Microsoft Ads: Conversion measurement for sign-ups, trial starts and paid PRO invoices, subject to the same cookie choice
We do not sell, rent, or trade your personal information to third parties for marketing or advertising purposes.
5. Data Storage & Security
Account data is stored on Cloudflare's edge infrastructure (Workers KV and D1) within Cloudflare's global network. Passwords are hashed using PBKDF2 with 100,000 iterations. Sessions use cryptographically random tokens with 7-day expiry. All connections use TLS encryption. Payment data is handled entirely by Stripe and never touches our servers.
6. Cookies & Local Storage
VectorWX uses a session cookie (vectorwx_session) for authentication. We also use local storage to save your layer preferences, map position, and UI settings.
Advertising conversion measurement. We use the Google tag (Google Ads) and, when configured, Microsoft UET to learn which of our ads lead to a sign-up or a PRO upgrade. When you allow it, Google may set cookies and receive data about your visit, such as the pages you view, your IP address, your browser, and the fact that you signed up or upgraded. With your advertising consent, the Google tag also uses your email for enhanced conversion matching. We use this data to measure and improve our ads.
With advertising consent, we save the first landing page's ad click IDs and campaign parameters in local storage. At account creation, we save them with your account. A later visit does not replace this first touch. Declining clears the browser's saved attribution and stops further collection.
Your choice. In the EEA, the UK, Switzerland, and when we cannot tell your country, this measurement is off until you click Accept on the cookie banner. Elsewhere it is on by default. You can change your choice at any time with Cookie Settings. We store your choice in a vwx_ad_consent cookie and in local storage, and your country (from our network provider, Cloudflare) in a vwx_cc cookie for one day.
To learn how Google uses this data, see policies.google.com/technologies/ads.
