Privacy Policy

Last updated: October 12, 2026

1. Information We Collect

Account and sign-in information

• Your name and email address
• Your password, if you sign up with email. It is stored hashed by our sign-in provider (Google Firebase Authentication), never in plain text, and we can never see it.
• If you sign in with Google or Apple, the name and email address that provider shares with us. With Sign in with Apple you can choose to hide your email, in which case we receive an Apple relay address instead.
• An internal account ID that links your data to your account

Content you create

• Watchlists, alerts, chart drawings, indicators, layouts, templates and settings
• Notes and trading journal entries
• Custom indicators and scripts you build, paste, convert or save
• Feedback you send us, including AI responses you choose to report

This content is saved to your account so it syncs across your devices. It is private to you.

AI assistant

When you use the AI assistant or other AI features, your message, the relevant chart and market data, and any chart image or voice recording you choose to share are sent to an AI service to generate a response (see section 4). We do not save your AI conversations. If you report a response with the thumbs down button, that conversation is emailed to our support team so we can review it, and it is kept in our support inbox.

Usage information (Google Analytics)

We use Google Analytics, through Google Firebase, to understand how the Service is used: which pages and features are opened (for example, that the screener was used), the type of device, browser and operating system, the app version, and approximate location at the country or city level. Google Analytics uses a random identifier stored in a cookie or on your device. We do not send Google Analytics your name, email address or account ID, and we use it only for our own statistics, not for advertising.

Sign-in and security records

Each time you sign in, we record the date and time, your IP address, your browser or device type, and the approximate location (country, region and city) derived from your IP address. We use these records to keep your account secure and to detect fraud and abuse.

Subscription and payment information

• On our website, payments are made directly to Stripe, our payment processor. Stripe collects your card details; we never see or store your full card number. We receive and keep your subscription status, plan, renewal date and a Stripe customer reference.
• In the iOS and Android apps, purchases are made through Apple's App Store or Google Play. We never receive your card details. We receive your subscription status, plan and renewal dates through RevenueCat, the service that confirms in-app subscriptions for us.

Notifications

If you allow notifications, your device gives us a push notification token so we can deliver the alerts you set up. We use it only for your alerts.

Information we do not collect

We do not collect your contacts, photos, files, precise location, health information or advertising identifier. We do not use advertising or tracking cookies. Face ID, Touch ID and fingerprint unlock happen entirely on your device; we never receive any biometric data.

2. How We Use Your Information

• To provide the Service: charts, alerts, watchlists, the AI assistant and syncing your data across your devices
• To deliver the alerts and notifications you set up
• To process your subscription and restore purchases
• To send account and billing emails, such as a receipt or a failed payment notice, and the alert emails you turn on
• To answer support requests and review reported AI responses
• To understand which features are used so we can improve them
• To keep accounts secure and to prevent fraud and abuse
• To comply with the law

We do not use your information for advertising, we do not build advertising profiles, and we do not track you across other companies' apps or websites.

3. We Never Sell or Share Your Information

We never sell, rent or trade your personal information, and we never share it with any company for that company's own purposes, including advertising, marketing or data brokering.

To run the Service, we use a small number of service providers listed in section 4. They store or process information only on our behalf, to provide their service to us, and only the information needed for that service. The payment and sign-in companies you choose to use (Stripe, Apple and Google) handle your payment and sign-in details directly, under their own privacy policies.

The only other time we would disclose information is if the law requires it, for example a valid court order. We will not disclose your information for any other reason.

4. Service Providers

• Google Firebase: sign-in, our database, push notification delivery and Google Analytics (Google Privacy Policy)
• Cloudflare: hosting, content delivery and security for the website and our servers (Cloudflare Privacy Policy)
• Stripe: website payments (Stripe Privacy Policy)
• Apple and Google Play: in-app purchases, Sign in with Apple, Google sign-in and push notification delivery
• RevenueCat: confirms in-app subscriptions (RevenueCat Privacy Policy)
• OpenAI, Anthropic and Google: generate AI responses from the content you send to the AI assistant
• Resend: sends our account, billing and alert emails

5. Cookies and On-Device Storage

The website and apps use cookies and on-device storage to keep you signed in, remember your settings and charts, and run Google Analytics as described above. We do not use advertising cookies. You can clear cookies and site data in your browser, but you may be signed out and lose settings stored only on that device.

6. Data Security

• All information is sent over encrypted connections (HTTPS)
• Passwords are hashed by our sign-in provider and never stored in plain text
• Access to user information is limited to what is needed to run and support the Service

No method of sending or storing information is completely secure, so we cannot guarantee absolute security.

7. Data Retention and Account Deletion

We keep your information for as long as your account is open. You can delete your account at any time in the app or on the website under Profile → Account → Delete Account, or by following the steps on our account deletion page, which also explains how to ask by email if you no longer have the app.

Deleting your account permanently deletes your account and everything tied to it: your profile, watchlists, alerts, notes, drawings, layouts, saved indicators and scripts, settings, push notification tokens and sign-in records. Requests made by email are completed within 30 days. Google Analytics statistics are not linked to your account and are kept by Google under our Google Analytics retention setting.

We may keep limited records where the law requires it, such as transaction records needed for tax and accounting. Payment processors (Stripe, Apple and Google) keep their own records under their own policies.

Deleting your account cancels a subscription bought on our website. It does not cancel a subscription bought through the App Store or Google Play; cancel those in your Apple ID settings or in Google Play to stop billing.

8. Your Choices and Rights

• Access and export: ask for a copy of your personal information
• Correction: update your name in account settings, or ask us to correct other information
• Deletion: delete your account as described in section 7
• Notifications: turn alerts and push notifications off in the app or in your device settings
• Emails: turn off alert emails in your settings, or ask us to stop any non-essential email

Depending on where you live (for example the European Economic Area, the United Kingdom or California), you may have additional rights under local law, including the right to object to or restrict how we use your information. We do not sell or share personal information as those terms are defined under California law. To make a request, email support@chartinglens.com. We will respond within 30 days.

9. Children's Privacy

The Service is not intended for anyone under 18, and we do not knowingly collect personal information from children. If you believe a minor has given us personal information, contact us and we will delete it.

10. International Users

We are based in the United States. Our service providers may process information in the United States and other countries. We protect your information as described in this policy wherever it is processed.

11. Changes to This Policy

If we change this policy, we will update the date at the top. If a change is significant, we will tell you in the Service or by email before it takes effect.
