Hey Product Hunt! 👋

I'm Riku, and I built Latch because I lost $273 last year to subscriptions I forgot to cancel.

Planet Fitness (impossible to cancel online), Adobe (surprise early termination fee), and 3 SaaS tools I signed up for during "free trials."

I thought I was just being careless.

Then I looked at the FTC data: 76% of subscription companies use dark patterns on purpose.

Hidden cancel buttons. Confusing workflows. Required phone calls. It's not accidental. It's by design.

THE PROBLEM:

Every month, you're locked into subscriptions that made sense 6 months ago but don't anymore.

That $9.99 tool you used once? Still charging you.

That gym membership? Still auto-renewing.

That annual domain? Forgot it was coming up.

Most subscription trackers "solve" this by:

❌ Requiring full bank account access (Rocket Money, Truebill)

❌ Charging $6-12/month (or taking 30-60% of your "savings")

❌ Selling your financial data to advertisers

There had to be a better way.

---

THE SOLUTION:

Latch is a Chrome extension that tracks subscriptions and reminds you BEFORE you're charged.

✅ Auto-detects subscriptions (Gumroad, Stripe, Vercel - more coming)

✅ Shows monthly burn rate ("You're locked into $247/month")

✅ 3-day advance notifications (never forget to cancel again)

✅ Manual add/edit (track existing subscriptions)

✅ Privacy-first (all data stays on your device, no servers)

---

WHAT MAKES IT DIFFERENT:

Rocket Money:

- Requires bank account access

- $6-12/month ($72-144/year)

- Takes 30-60% of negotiated "savings"

- Closed source

Latch:

- Email-only (no bank access needed)

- Free tier (up to 8 subscriptions)

- Pro tier: $39/year for unlimited

- Open-sourcing code next week

PRICING (Honest & Transparent):

FREE TIER (covers 80% of users):

✅ Track up to 8 subscriptions

✅ Monthly burn rate display

✅ 3-day renewal notifications

✅ Manual add/edit/delete

✅ All core features

Average person has 5-7 subscriptions, so free tier covers most people.

PRO TIER ($39/year):

✅ Unlimited subscriptions

✅ Email scanning (auto-import from Gmail)

✅ Spending analytics dashboard

✅ Custom notification timing (1, 3, or 7 days)

✅ CSV export

✅ Priority support

One-time annual payment. No auto-renewal BS (that would be ironic).

Why not free forever?

I could've:

❌ Required bank access and monetized your financial data

❌ Taken 30-60% of "savings" like Truebill

❌ Injected ads or sold browsing data

Instead: Transparent pricing. Free for casual users. Paid for power users.

If you're tracking 15+ SaaS tools, $39/year ($3.25/month) to NOT give someone your bank login = fair trade.

---

THE PHILOSOPHY:

"Every subscription must justify its existence."

Not once when you signed up.

EVERY. SINGLE. MONTH.

If it's not worth $X/month RIGHT NOW, cancel it.

Latch makes that decision easier.

---

TECH DETAILS (for the builders):

- Chrome extension (Manifest V3)

- Plasmo framework

- Background service worker for notifications

- chrome.storage.sync (cross-device, zero backend)

- chrome.alarms for scheduled checks

- DOM parsing for price/service detection

Zero external servers. All data local. Open-sourcing this week on GitHub.

BUILT IN PUBLIC:

I've been documenting the entire journey on Instagram @build.signal

- Daily progress updates

- Honest metrics (including my previous project: 87 views, 0 sales)

- Code snippets and architecture decisions

- Real-time debugging

No BS. No fake screenshots. Just the actual journey.

I'M HERE ALL DAY:

Ask me anything about:

- Technical architecture (MV3, service workers, storage)

- Privacy model (why local-first matters)

- Monetization (why freemium vs bank access)

- Build-in-public journey (what worked, what didn't)

- Feature requests (what should I build next?)

Thanks for checking it out! 🔥
