ZeroReturn helps you file your Bangladesh income tax return with a licensed tax agent, end to end,
from your phone. This policy explains what information we collect to do that, how we use it,
who we share it with, and the choices you have.
01
Who this policy covers
This policy applies to everyone who uses the ZeroReturn Android app to prepare, submit, or track
a Bangladesh income tax return. By creating an account, you agree to the collection and use of
information as described here.
02
Information we collect
We only collect what's needed to verify who you are, prepare an accurate return, and keep you updated on its progress.
Account & identity information
Mobile numberVerified by SMS one-time code when you sign in with a phone number.
Google accountName and email address, if you choose to sign in with Google instead.
Full name & addressAs it should appear on your return.
OccupationUsed to prepare the right category of return.
Tax & filing information
Uploaded documentse-TIN certificate, bank statements, salary certificate, investment proof, and any other document your assigned agent requests, as photos or PDFs.
Package & pricingThe filing package you choose and its price.
Calculator inputsIncome, taxpayer category, and investment figures you enter into the in-app tax calculator.
When you pay by bKash or Nagad manual transfer, we ask for the transaction ID you receive after
sending money, so your agent can confirm it. When card or wallet payment is available through a
payment gateway, that gateway processes your card or wallet details directly — ZeroReturn does not
see or store your card number, PIN, or wallet password at any point.
Support communications
Messages you exchange with your assigned tax agent through the in-app chat, so they can help with your filing.
Device & usage information
A push-notification token so we can tell you when your status changes, and general, aggregated app
usage data (screens visited, feature usage, crash diagnostics) collected through Firebase Analytics
and Firebase Cloud Messaging.
What we don't collect
We don't access your contacts, photo library beyond the document you choose to upload, or precise
location. We don't request access to unrelated device data.
03
How we use it
To verify your identity and keep your account secure.
To prepare, review, and submit your income tax return through your assigned agent.
To confirm manual payments and keep an accurate record of what you owe and what's been paid.
To send status updates about your filing (document requests, review results, submission, acknowledgement).
To respond to messages you send through in-app support.
To diagnose crashes, understand which features are used, and improve the app.
04
How it's shared
Your information is shared only where it's needed to file your return or run the service — never sold,
and never shared for advertising.
With the licensed tax agent or staff member assigned to your case, so they can prepare and review your return.
With the National Board of Revenue (NBR), as part of the return your agent files on your behalf, exactly as any tax preparer would.
With the infrastructure and platform providers listed below, who process data on our behalf under their own security and privacy commitments.
05
Third-party services
ZeroReturn is built on the following services:
Google Sign-In
Optional sign-in method
Firebase Cloud Messaging
Push notifications
Firebase Analytics
Aggregated app usage & crash data
Each provider processes data under its own privacy policy, in addition to the commitments made here.
06
Storage & security
Your data is stored on a managed infrastructure and transmitted using encrypted (HTTPS/TLS)
connections. Access to your records is restricted by row-level security rules, so only your own
account and your assigned agent can read your information — no one else's account can see it.
No method of storage or transmission is completely without risk. We work to protect your information
but can't guarantee absolute security.
07
Retention
We keep your account and filing information for as long as your account is active, and afterward for
as long as Bangladeshi tax recordkeeping rules require. You can ask us to delete your account at any
time, subject to those legal retention requirements.
08
Your rights
You can, at any time, ask us to:
Show you the personal information we hold about you.
Correct information that's inaccurate or out of date.
Delete your account and associated data, except records we're legally required to keep.
Reach us using the contact details below to make any of these requests.
09
Children's privacy
ZeroReturn is a tax-filing service and is not directed at, or intended for use by, anyone under 18.
We do not knowingly collect information from children.
10
Changes to this policy
If we make material changes to this policy, we'll update the effective date above and notify you
in the app before the changes take effect.
