Splash is free. Here's why that works.
Your phone does the work, so running Splash costs very little. No premium tier, no trial, and no selling data.
In short: Splash is free. There is no premium tier, no trial and no in-app purchases: partner sharing, the doctor report, insights, every mode and the full library cost nothing. It stays cheap to run because your data lives on your phone, and backups are small encrypted files. We never sell your data.
| Part | Where it runs | Cost |

| Tracking, predictions, insights, library | Runs on your phone | Costs us nothing per user |
| The website and app files | Served from a CDN | Pennies per thousand visits |
| Encrypted sync and sharing | Small locked files on EU servers | The main cost, and small |
| Notifications | Sent by a push service | Tiny |
Paid elsewhere. Free here.

Questions
Is Splash really free?
Yes. Every feature is free: sharing with the people you choose, the doctor report and clinician links, Lock Screen timers on iPhone, pregnancy and perimenopause modes, the full library and sync. There is no premium tier and no trial.
Could pricing change later?
Everything in Splash is free to use right now. If pricing ever changes, we will say so clearly in advance on this page and in the changelog, and you can always export a full backup of your data.
Do you sell my data?
No. There are no third-party trackers in Splash and we never sell your data. With no account, nothing about your cycle reaches us. With sync on, we only hold an encrypted copy we cannot read.
How is it free?
Splash runs on your phone, so most of the work costs us nothing. Sync stores small encrypted files, which is cheap. The team covers hosting.
