Terms & disclaimer

Terms of Use

Effective date: November 11, 2026
Website: https://aumahinay.dev

These terms explain how you may use aumahinay.dev (“Website”) and what its content is, and is not, meant for. By using the Website, you agree to them.

1. For Learning Only

The blog posts, study notes, tutorials and tools on this Website are written to help readers understand local treasury work, public finance, Python programming and online safety. They are general information for learning. They are not legal, tax, accounting or financial advice, and they are not an official ruling or opinion of any government office.

Laws, rates and procedures change, and local ordinances differ from place to place. Always check the current law, your local revenue code and the office concerned before you act on anything you read here.

2. The RPT Calculator

The real property tax calculator is a study aid. Its results are estimates based on the rules described on its page. Your actual tax depends on your tax declaration and your local ordinances, and your municipal, city or provincial treasurer's office has the final figures.

3. Exam Reviewers and Study Notes

The vocabulary modules and study notes are independent material written by the author. They are not official materials of the Civil Service Commission, the Bureau of Local Government Finance or any other office, they do not contain actual exam questions, and they do not guarantee any exam result.

4. Personal Capacity

Everything on this Website is written in the author's personal capacity, outside official working hours. It does not represent the views, policies or positions of any local government unit or national government agency.

5. Accuracy and Corrections

I check the facts before publishing and update pages when I learn of a change, but I cannot promise that every page is complete or current. If you spot an error, please write to me and I will check it and correct it.

6. Copyright

The writing, pictures and the ALTOS book preview on this Website belong to Ambrosio U. Mahinay unless stated otherwise. You may quote short parts with a link back to the page. Please don't copy or republish whole posts, notes or book pages without written permission.

The example code in the Python tutorials is there for you to learn from: you are welcome to use and adapt it in your own work.

7. Advertising and Links

This Website may show ads served by Google AdSense. Ads are chosen by Google, not by me, and an ad is not an endorsement. Links to other websites are given for your convenience; I am not responsible for their content. How ads and cookies work here is explained in the Privacy Policy.

8. Limitation of Liability

The Website and its tools are provided “as is”, free of charge. I am not liable for any loss or damage that comes from relying on its content or tools.
