Privacy Policy
Last updated: October 9, 2026
This Privacy Policy explains how MonthlyWise ("we", "us", or "our") handles information when you visit www.monthlywise.com (the "Site"). By using the Site, you agree to the practices described here.
Information we collect
Calculator inputs
The mortgage, auto loan, personal loan, credit card, and budget calculators run entirely in your browser. The numbers you enter are not sent to or stored on our servers.
Split Expenses groups
If you create a shared-expense group, we store the information you enter (group name, member names, expense descriptions and amounts) in our database so that you and the people you share the link with can access it. Anyone with the group link can view that group, so please do not enter sensitive personal information. You can ask us to delete a group at any time by contacting us.
Technical and log information
Like most websites, our hosting provider automatically receives standard technical information such as your IP address, browser type, device type, referring page, and the time of your visit. We use IP addresses briefly to prevent abuse (for example, rate-limiting how many groups can be created) and do not use them to identify you.
We use Vercel Speed Insights to measure page performance (such as load times). It collects anonymous performance data and does not use cookies.
Preferences stored on your device
We store your light/dark theme preference in your browser's local storage. This never leaves your device.
Cookies and advertising
We use Google AdSense to display advertisements on the Site. Google and its partners use cookies and similar technologies to serve ads based on your prior visits to this Site and other websites.
- Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to this website or other websites.
- Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to this Site and/or other sites on the Internet.
- You may opt out of personalized advertising by visiting Google Ads Settings. You can also opt out of some third-party vendors' use of cookies for personalized advertising at www.aboutads.info.
To learn more, see How Google uses information from sites or apps that use its services. Visitors in the European Economic Area, the United Kingdom, and Switzerland will be asked for consent before personalized ads are shown.
You can block or delete cookies through your browser settings. Doing so may affect how ads are shown but will not stop the calculators from working.
How we use information
- To provide and operate the Site and its features.
- To keep the Site secure and prevent spam or abuse.
- To display advertising that helps keep MonthlyWise free.
- To respond to messages you send us.
We do not sell your personal information.
Service providers
We rely on trusted providers to run the Site, including Vercel (hosting), Supabase (database for Split Expenses groups), Upstash (rate limiting), and Google (advertising). These providers process data on our behalf under their own privacy policies.
Your rights
Depending on where you live (for example, under the GDPR or the California Consumer Privacy Act), you may have the right to access, correct, or delete personal information we hold about you, or to object to certain processing. To make a request, email us at sumit.o4172@gmail.com.
Children's privacy
The Site is not directed to children under 13, and we do not knowingly collect personal information from children.
