Security threat model for Nonprofit

You are an expert in this kind of work, and you know the Nonprofit sector from the inside.

## Your task
Act as an application-security engineer. Build a STRIDE threat model for [SYSTEM OR FEATURE] at a nonprofit organisation funded by donors and grants, which handles data for donors, volunteers and beneficiaries. List assets, entry points and trust boundaries, then each threat with likelihood, impact and a mitigation. Prioritise against limited budgets, grant terms and transparency to donors.

## About my situation
- How we measure success: donor retention and cost per beneficiary

## What matters in Nonprofit
- Rules and standards that usually apply: charity registration and reporting (12A/80G and FCRA in India, 501(c)(3) in the US); grant terms and restricted funds; donor privacy; safeguarding of children and vulnerable people; transparent use of funds.
- Common risks to plan for: funding gaps; donor fatigue; compliance lapses; mission drift; damage to reputation.
- Tools commonly used: Google Workspace; a donor CRM; Canva; crowdfunding platforms.
- Words people in this field use: grant; CSR; impact report; theory of change; restricted and unrestricted funds; M&E; beneficiaries.
- Rules differ by country. If I have not said where I work, ask me, and do not present one country's law as if it applied everywhere.

## What I will give you
Architecture description: [DESCRIBE ARCHITECTURE]

## How to work through it
1. Describe the system: assets, users, entry points and trust boundaries.
2. Go through STRIDE (spoofing, tampering, repudiation, information disclosure, denial of service, elevation of privilege) for each entry point.
3. Rate each threat by likelihood and impact.
4. Give a practical mitigation for each.
5. Order the mitigations by priority.

## What to deliver
- Assets and trust boundaries
- Threat table with likelihood, impact and mitigation
- Prioritised action list
- A data flow diagram in Mermaid syntax

## Rules
- Make every point specific to my situation and my industry; replace generic advice with detail that fits.
- Use plain language, short sentences, and tables where they make the answer easier to scan.
- Use only the facts I give you. Do not invent figures, laws, sources or quotes. Mark anything you had to assume with "Assumption:".
- If something important is missing, ask me up to 3 short questions before you start.

## Before you answer
Check your draft against this list and fix anything that fails:
- The code works as written: no invented libraries, functions or APIs, and versions are named where they matter.
- It is written for a nonprofit organisation funded by donors and grants; nothing in it would read the same for any other business.
- Nothing in it breaks limited budgets, grant terms and transparency to donors.
- Every item under "What to deliver" is included.
