Where does my period data live?

On your iPhone. Only on your iPhone. Nowhere else. If your phone is lost, your data is lost — we can't recover it, because we never had a copy.

Is Dew a private period tracker?

Yes. Dew has no account, no email collection, no ads, no third-party trackers, and no data sold to anyone. Your cycle logs stay on your iPhone — we have no way of knowing who you are.

Does Dew use iCloud sync?

Optional. If you turn iCloud sync on, your data lives in your own private iCloud, encrypted so only your Apple devices can open it. We don't see it. Apple can't read it.

Where are insights generated — on my phone, or somewhere else?

Insights are written entirely on your iPhone by Apple's on-device language model. No prompts, no data, no outputs ever leave the device — no one but you can see them.

How much does Dew cost?

Dew is free during v1. When pricing arrives in v1.1+, there will be a small one-time price for core tracking and a small monthly Pro tier for advanced features. Both are honest. No surprises, no dark patterns.

Because accounts mean we'd have to keep something about you. We don't want to. The whole app is built so it's impossible for us to know who you are.

Why I built Dew

A short note from the maker. Why a calm, private period tracker — and the line I won't cross even if it costs me users.

I'm Abhishek. I make Dew. This is a short note about why.

Before this, I spent years at Cityflo — a transit company in Bombay where my job was building the app commuters opened every morning. I learned the discipline of being someone's calm first-thing-in-the-morning ritual, where one bad notification can ruin a Monday. The lesson was: most apps shout. The best ones whisper.

Dew is the whisper version of a period tracker.

Why a period tracker

Honestly: because the category felt wrong. Period apps in 2024 had become some of the loudest, ad-funded, data-hungry consumer software in the App Store. Cycle data — which is intimate by definition — was being treated like ad inventory. The FTC had fined Flo. The Markup had written about Stardust. Mozilla had labeled most of the top apps "privacy not included."

And separately, post-Dobbs, people were quietly switching to Apple Health Cycle Tracking or Euki because they wanted their cycle data to be unreachable to prosecutors. The need for a calm, private tracker that didn't make people choose between a real diary and structural privacy was clear.

I wanted to build the small, quiet, gentle one. So I did.

The line I won't cross

Dew will never have a server that stores your cycle data. Not for sync, not for backup, not for analytics, not for AI features, not for partner sharing, not for anything. Sync happens through your own iCloud Private Database — end-to-end encrypted with your keys, invisible to me. The architecture is the protection, not the promise.

This is the line I won't cross even if it means lower retention numbers, smaller userbase, or worse press. The whole point of Dew is that the privacy claim is structural — if I could break it, it wouldn't be a real claim.

What Dew isn't

Dew is not a medical device. It doesn't diagnose. It doesn't claim to prevent pregnancy. It doesn't tell you when you're fertile with clinical certainty. There are apps that do those things (Natural Cycles is the FDA-cleared one) — and that is a different product with different responsibilities.

Dew is a calm, private cycle diary. It helps you notice the patterns in your own body. The clinical questions — should I see a doctor, am I in a normal range, is this PMDD or PMS — those still belong with a doctor, and I'd never want a tracker to replace that conversation.

How Dew makes money

Honestly. Dew is free during v1. The plan from v1.1 onward is a small one-time purchase plus an optional monthly Pro tier for advanced features (multi-profile, partner sharing, richer insights). No ads. No data monetization. No "sponsored content" inside the app.

The unit economics work because Dew is a small studio with low overhead — no team to feed, no investors to grow for. If 10,000 people end up paying $10 once and 1% pay for Pro, that's enough to keep building. It doesn't need to be a unicorn. It just needs to be sustainable.

The personal version

I have people in my life who use period trackers daily. When I told them what was actually happening to their cycle data in most of the apps they were using, the reactions were a mix of "I had no idea" and "I assumed, but didn't want to think about it." Neither of those reactions is OK in 2026.

Dew exists because that conversation should have a different ending. "Yes, you're tracking. No, no one else can see it. Yes, it stays yours."

What to expect from here

Small, frequent updates. A v1.1 with partner sharing through Apple's secure share sheet (still encrypted, still no server). A v1.2 with smarter on-device reflections using Apple's local LLM (so even the AI features never leave your phone). And a continuing journal — short, honest writing about why the app is built this way and where it's going.

If you want to follow along: there's no newsletter. I won't ask for your email. Dew is calm here too — open the App Store page when you want to see what's new, and if you have thoughts, email me at [email protected]. I read everything.
