Terms of Service.
Clear & Fair.

Agreements for Guest usage, Registered Accounts, and Premium Subscriptions. We prioritize transparency in how we operate.

1. Accounts & Registration

Security: If you create an account, you are responsible for maintaining the security of your password. You notify us immediately of any unauthorized use of your account.

Eligibility: You must be at least 13 years old to register. We reserve the right to suspend or terminate accounts that violate these terms or engage in abusive behavior (e.g., botting).

2. Premium Subscriptions

  • Billing: Premium features (such as AI Chat, Ad-free experience, and Cloud History) are billed on a recurring subscription basis.
  • Cancellation: You may cancel your subscription at any time via your account settings. Access to premium features will continue until the end of the current billing cycle.
  • Refunds: Refunds are handled on a case-by-case basis or according to local laws. Generally, we do not offer refunds for partial months.

3. AI Features & Usage

Our "AI Chat" and "Smart Explain" features use artificial intelligence to assist with calculations. By using these features, you acknowledge:

  • •AI may produce inaccurate or "hallucinated" results. Always verify AI outputs with the standard calculator tools.
  • •You should not share sensitive personal information (PII) like social security numbers or private health data in the AI chat.

4. Intellectual Property

The calculator algorithms, website design, and "LogitCalculator" brand are owned by us. However, the data you generate (your calculation history) belongs to you. We claim no ownership over the specific financial or scientific inputs you process through our tools.
