Switch Karle
Everything about an Indian job switch except finding the job.
From "I'm done here" — before you have applied anywhere — through the offer, the
resignation, ninety days of notice, and surviving the first three months at the
new place.

Free and open source. Every number runs in your browser. Nothing is uploaded. No
accounts, no analytics, no AI calls.
You find openings on Naukri or LinkedIn. We do not do job listings, resumes, ATS
scoring or interview banks, and we are not going to — see PRODUCT.md
for what that decision is and why.

Privacy is a promise, not an architecture
- 100% client-side. No server, no accounts, no analytics. Your offer never leaves this device.
- No AI calls. Bring your own AI: the app generates prompts you paste into ChatGPT/Claude/Gemini.
- Data lives in
localStorage under switchkarle.<tool>.v<N>, with JSON export/import on the Tracker.
The engineering rule behind these promises, and what it would take to change one, is in PRIVACY.md.
Tax engine
Pure TypeScript, golden-tested against hand-computed cases (src/engine/engine.test.ts). FY 2026-27:
- New regime: slabs ₹0–4L nil → 30% above ₹24L; ₹75,000 standard deduction; rebate (zero tax to ₹12L taxable) with marginal relief; surcharge tiers; 4% cess.
- Old regime: ₹50,000 standard deduction, HRA exemption, 80C/80D, professional-tax deduction.
- EPF 12% of basic (statutory-ceiling option), gratuity accrual 4.81%, state professional tax (approximate).
Estimates, not tax or legal advice. Footer chip shows when the rules were last verified. A practising CA is reviewing the constants; until then statutory tools ship as provisional-pending-CA.
