Privacy Policy
Last updated: July 17, 2026
1. What we collect
To give you an account and save your work, Meridary stores your account email and the plan inputs you enter — ages, balances, income, and assumptions. That is the data you choose to type in.Meridary does not ask for account numbers, and never sees them.
2. No bank aggregation
Meridary does not link to your bank, brokerage, or any outside account. There are no credentials to hand over and no third-party aggregation service. You enter what you choose, and your plan is yours.
3. Computed in your browser
The projection and Monte Carlo simulation run locally in your browser, not on our servers. Your plan is saved to your account so you can return to it, but the modeling itself happens on your own device.
4. We do not sell your data
Meridary does not sell, rent, or trade your personal information or plan data to anyone. We do not run advertising and have no interest in monetizing your financial details — you paid for the tool once, and that is the business model.
5. Service providers
A few providers process data on our behalf so the product can function: Stripe handles payments (we never see your card number), Better Auth manages sign-in and sessions, and PostHog provides product analytics. PostHog records pageviews, clicks, and errors under your account so we can find and fix problems; session recordings mask the contents of every form field, so the figures you type are not captured.
6. Your data
You can delete your plans at any time, and you can request deletion of your account and its data by contacting us. We keep your data only as long as your account is active or as needed to provide the service.
