Privacy Policy
Last updated 25 May 2026
DividendMapper ("we", "us") provides dividend portfolio tools for UK and US investors. This policy explains what personal data we collect, why we collect it, and your rights under UK GDPR. We are the data controller. For any privacy question, email hello@dividendmapper.com.
What we collect
Account details. Your email address. We use it to sign you in (we use passwordless magic links and one-time codes, not passwords) and to send you service emails.
Portfolio data. The holdings, amounts, and account types you choose to enter. You decide what to add, and you can delete any of it at any time.
Subscription and payment data. If you upgrade to Pro, our payment processor handles your card details. We never see or store full card numbers. We keep a record of your subscription status and a Stripe customer reference.
Usage and diagnostics. Basic analytics about how the app is used, and error reports when something breaks, so we can fix problems and improve the product.
Who processes your data
We use a small set of trusted providers, each acting on our instructions:
- Supabase for our database and authentication, which stores your account and portfolio data.
- Stripe for payment processing and subscription billing.
- Resend for transactional emails such as sign-in links, receipts, and account notices.
- PostHog for product analytics.
- Sentry for error monitoring.
- Vercel for application hosting.
Some providers may process data outside the UK. Where they do, they rely on appropriate safeguards such as the UK International Data Transfer Agreement or equivalent.
Why we can use your data
We rely on two legal bases. To provide the service you asked for (performing our contract with you): running your account, storing your portfolio, and billing Pro subscriptions. And our legitimate interests: keeping the app secure, fixing errors, and understanding usage so we can improve it.
How long we keep it
We keep your account and portfolio data for as long as your account is open. When you delete your account, we delete your profile, holdings, and subscription records. Some limited records, such as payment records that Stripe must retain for tax and accounting, may be kept by our providers as required by law.
Your rights
Under UK GDPR you can ask us to access the data we hold about you, correct it, delete it, restrict or object to how we use it, or provide it in a portable format. You can delete your account, and all the data tied to it, yourself from the Account page at any time. To exercise any other right, email hello@dividendmapper.com. You also have the right to complain to the Information Commissioner's Office at ico.org.uk.
Cookies and analytics
We use essential cookies to keep you signed in, and analytics to understand which features are used. We do not sell your data and we do not use it for third-party advertising.
Changes
We may update this policy as the product changes. The "last updated" date above always shows the current version.
