How to cancel Phioo by mail
Get your account details together
Have the name and email on the account and, if you have one, an account or customer number to hand. The details in the letter need to match what Phioo has on file.
Draft the request
Your Postbye letter to Phioo asks for three things: the account closed, no further charges and a written confirmation, all under “Subject: Subscription termination – Phioo”. It comes from our English template.
Post it with proof of delivery
Use certified mail for the 94104 San Francisco address in the next section, so the post office records the delivery. Write down the tracking number.
Save the tracking record
It shows the date Phioo received your letter. Check your next statement: no Phioo charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Phioo cancellation letter goes
Phioo can be reached by post at 369 Pine St, Suite 410, San Francisco, CA 94104.
San Francisco, California 94104 is a United States address, so ordinary certified mail reaches it.

Before you cancel Phioo, check these
- If an app store or phone carrier bills you, the company cannot cancel it. Cancel with that partner as well.
- Cancelling usually ends access at the end of the period you paid for, so you keep what you paid for until then.
- Use the same name and email as on the account. A mismatch can delay the request.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

How cancelling by mail works
Most subscriptions keep billing until someone tells the company to stop, and a dated letter is proof that somebody did.
If a charge shows up after you cancelled, the letter and its receipt are what you put in front of the company or your bank.
