Support OIR

Open Internet Reference is a free, evidence-based knowledge base. Traffic and hosting costs grow as more people use the site.

If you find this site useful, you can buy me a coffee. Tips are optional one-time support through Buy Me a Coffee and help cover hosting, domain, and maintenance time.

Buy me a coffee

What tips are (and are not)

Not tax-deductible

Tips sent through Buy Me a Coffee are personal support for the maintainer and this reference project. They are not charitable donations to a registered nonprofit, and they are not tax-deductible in the United States or elsewhere unless your tax adviser tells you otherwise.

  • Tips are voluntary and do not unlock special access or editorial influence.
  • OIR remains free to read; tips do not buy placement in the knowledge base.
  • For tax-deductible support of digital-rights work, use the Organizations listed in OIR (for example EFF, ACLU, or Knight First Amendment Institute), not this tip jar.
