A family searching for blood at midnight will believe almost anyone who says yes. That's why the safety rules on Dropli are built into the app instead of written in a policy nobody reads.

Scam shield
Someone says they can donate, then asks for bKash or Nagad money for transport, a test, or "the hospital fee" before they come. They never come. When a chat message asks for money or includes a mobile banking number, Dropli puts a warning under it, on both phones.
“সতর্কতা: রক্তদানের জন্য টাকা চাওয়া প্রতারণা হতে পারে। Dropli কখনো টাকা লেনদেন করতে বলে না।”
The warning, as it appears in the app.

Money on Dropli
There are exactly two places in Dropli where anyone pays anything. Neither of them reaches a donor.
Not by Dropli, not by the family, not "for transport". Blood is given, never sold.
৳200 or ৳500 to reach donors 30 or 60 km away. It covers SMS and voice calls, nothing else.
After a donation a family can chip in to keep Dropli running. It's paid through SSLCommerz, inside the app, never to a person in chat.
If a message that claims to be from Dropli asks you to send money, it isn't from us. Report it.
Verified donations
Anyone can claim they gave blood. On Dropli a donation is only marked verified after the patient's family types in a code from the donor's phone. That's what makes passports and certificates mean something.
At the hospital, the normal way. Dropli isn't involved in the medical part.

Six digits and a QR on their phone. They're told not to share it before donating.

"Did Karim give blood?" They type the six digits, or scan the QR.

Each verified donation gets a certificate number and a QR link that confirms it.

What it looks like on the family's phone.
If a donor shared the code before donating, a family could mark the donation done and close the request while still short of blood. So the app tells donors to show it after, and families to ask for it after.
No code at all? The family can still close the request. The donation just won't be marked verified.
Privacy
Your location is used to work out distances. It isn't shown to other people. Here's what each side of a request can and can't see.
| Information | The family who asked | A donor | A hospital console |
|---|---|---|---|
| Where a donor lives | No.Only a distance, like "3.9 km away". | Their own, to work out distances. | No.Only counts per small map area. |
| A donor's name | Yes,once that donor says they can give. | Their own. | Noon the supply map or in impact reports. |
| The request | Their own. | Yes.Group, bags, hospital, date and urgency, so they can decide. | Yes,for requests the institution posted. |
| The family's phone number | Their own. | After a check.On a shared link, only after the donor confirms with an emailed code. | No. |
| Donation records | Whether the donor's code was entered. | Yes,on their passport and certificates. | Totals only.Impact reports carry no donor's personal details. |
The hospital supply map
Blood banks want to know how many donors of each group live nearby. They don't need to know who or where. The supply map answers the first question and refuses the second.

Habits that help
Not for transport, food, a test or anything else. Real donors don't ask.
At the blood bank or the ward. Not at a shop, not at a bus stop.
That's where the warnings and reports work.
Enter the donor's six digits once they've actually given.
The hospital tests and cross-matches the blood. Dropli only finds the donor.
A family stops looking once the bags are covered.
Show it after you've given blood, never before.
Even if it's offered kindly. It's the line that keeps scammers out.
Medication, illness, travel. The screening is there for the patient and for you.
Dropli won't alert you before then. Don't go around it.
Reporting
Open the conversation, tap the info button, and choose report. Write what happened in a few lines (at least ten characters, so we know what to look at). It goes to the Dropli team to review.

No. Nobody on Dropli may ask for money to donate blood, for any reason. Don't send it. Report the person from the chat and wait for another donor.
No. Donors see the hospital where blood is needed. Your own location is only used to calculate distances and isn't shown to other users.
It can see how many eligible donors of each group live in small areas around it. It can't see names, IDs or exact locations, and areas with fewer than three donors of a group are hidden.
The patient's family entered the donor's six-digit code (or scanned their QR) after the donation. Only then is it marked verified on the donor's passport and certificate.
No. Dropli finds donors. Screening, testing and cross-matching happen at the hospital or blood bank, the same as always.
