Habstack
Built in India · Privacy-first

Save quietly.
Save together.

What's inside

Designed for savers, not spenders.

👁️

Stealth Mode

Amounts blur on the dashboard. Only percent-complete is visible — so you can open the app on a crowded train.

⚡

Streak Engine

3-day streaks unlock fire mode. Miss a day and your streak repairs once — no toxic perfectionism.

🎯

Goal Tracking

Name your goal — Bike, Goa trip, emergency fund. Habstack adapts the calendar and the math to your dream.

🔒

Privacy Lock

4-digit PIN gate. Your vault, your secret. No backend can read your goals or amounts.

The viral hook

Save with a partner.
Without exposing balances.

Create a joint goal, share a 6-letter code, and start saving in lockstep. Both of you save independently, but the goal progress stays in sync via Supabase Realtime.

  • ✓ Codes look like PP-3VG4PD — share over WhatsApp
  • ✓ See your partner's contributions live
  • ✓ Either can leave; their share gets archived cleanly
  • ✓ No one sees actual rupee amounts unless you choose to share
Works with what you already use

UPI, demat, liquid funds — your choice.

Habstack tracks your savings habit. The actual money moves through your existing bank account or a SEBI-registered demat platform. We never hold your funds.

Zerodha
Groww
Upstox

Privacy isn't a feature. It's the foundation.

Your goals, amounts, streaks — all live on your device, encrypted with your 4-digit PIN. Joint-goal sync uses anonymous Supabase auth: no email, no phone number leaves your device until you opt in.
