SpliTTime Privacy Policy

Effective: June 8, 2026.

This policy covers the SpliTTime iOS app: what it collects, how that gets used, and which outside services touch your data. SpliTTime is a cell-culture management tool from TetraGammaTron Labs, sold on the Apple App Store for iPhone and iPad.

What SpliTTime Does

SpliTTime does the cell-culture math for you. It works out doubling time from your counts, projects when a culture will hit a target density, and figures out when to seed back so cells are ready for a Monday-morning experiment. Save a profile for each line you grow, whether that's HEK293, CHO, a primary line, or something custom, and the app keeps its observations, history, growth charts, and summary stats. There's no account and no sign-in.

Information We Collect

The lab data you type in stays in the app on your device and drives the calculations. That covers your profiles, counts, observations, doubling times, notes, and projections. We don't ask for your name or email, and there's no account to create.

The ad and system parts of the app do collect some technical data on their own. That can include a device or advertising ID, IP address, rough location, device model, iOS version, language, app version, and how you interact with ads. The next section explains it.

Advertising (Google AdMob)

SpliTTime is free and pays for itself with ads served through Google AdMob and the Google Mobile Ads SDK. To show and measure those ads, Google's services may collect technical data: a device or advertising ID, IP address, rough location, device model, iOS version, language, app version, and ad-interaction data.

Google says apps that use its ad services may share details like the app's name and a unique advertising identifier with Google. Its full ad practices are in its own policies, including How Google uses information from sites or apps that use its services. To check or change your ad-personalization settings, go to Google My Ad Center.

The ad SDK only handles ads. It never sees the lab data you enter, so your profiles, counts, notes, and projections stay out of it.

App Tracking Transparency (IDFA)

Before iOS lets an app track you using the advertising identifier (IDFA), Apple makes the app show its App Tracking Transparency prompt. Allow it and the ads get more personalized. Decline and you still see ads, just less targeted ones. You can change your mind anytime in Settings, under Privacy & Security and then Tracking, where you can also reset or limit the identifier.

The Pro Upgrade

There's a one-time Pro upgrade that turns the ads off and helps fund the work. Apple runs the sale through StoreKit, so we never see your card, billing address, or Apple ID. Apple's privacy policy covers that part: apple.com/legal/privacy. Once Pro is active, the AdMob SDK stops running.

Calendar Export

SpliTTime can hand predicted events to your iOS Calendar as standard ICS files, things like a target-density reach, a harvest, or a seed-back. That only happens when you ask for it, and your device's own Calendar does the rest.

How Information Is Used

The data the app handles goes toward running your calculations, showing and measuring ads in the free version, processing the Pro purchase, and keeping the app working. We don't sell your personal information.

Third-Party Services

The only outside parties involved are the ones that serve ads and process the Pro purchase. Each runs under its own privacy policy:

Children's Privacy

SpliTTime is built for lab and research work, not for kids. It isn't aimed at children under 13, and we don't knowingly collect their personal information.

Your Choices and Data Deletion

  • Want your SpliTTime data gone? Delete a profile in the app, or remove the app to wipe its local data.
  • For ad personalization, use the App Tracking Transparency prompt and the ad controls in iOS Settings, or head to Google My Ad Center.
  • To manage the Pro purchase or ask for a refund, use your Apple ID settings or go to reportaproblem.apple.com.

Changes to This Policy

If the way SpliTTime handles data changes, the updated policy shows up at this URL with a new effective date. Anything significant also lands in the app's release notes.
