1. Description of Service

Trajectory provides free online financial calculators, a personal finance simulator, and educational blog content. The Service is designed for informational and educational purposes only.

2. Not Financial Advice

Trajectory is not a financial advisor, tax professional, or licensed investment advisor. All calculators, projections, and content are provided for informational purposes only and should not be considered financial, tax, or investment advice. Results are estimates based on the inputs you provide and simplified assumptions. Always consult a qualified financial professional before making financial decisions.

3. Accounts

You may use many features of the Service without creating an account. To access Pro features, you must sign in with Google. You are responsible for maintaining the security of your account and for all activities that occur under it.

4. Free and Pro Plans

Free Plan

The Free plan provides access to all calculators, the financial simulator with one local scenario, and all blog content. The Free plan is supported by advertisements served by Google AdSense.

Pro Plan

The Pro plan is available as either a one-time lifetime purchase ($9.99) or a monthly subscription ($1.99/month). Pro features include unlimited cloud-saved scenarios, scenario comparison, additional charts and visualizations, chart export, custom themes, custom backgrounds, and an ad-free experience.
