Terms
Last updated 19 August 2026
These terms cover the Soleii app, this website, and any subscription you buy. Using Soleii means you accept them.
What Soleii is
Soleii is a cycle tracking app built for two people. One person logs their cycle. The other gets phase-aware context, prompts, and a way to help. Both sides need their own account.
Your account
Keep your login details to yourself, and tell us if someone else gets into your account. You’re responsible for what happens under it. You need to be 13 or older to use Soleii. You can delete your account at any time from Profile, then Account, and that deletion is permanent.
Partner links
Linking is invite-based, and you stay in control of it. Giving someone your invite code lets them see the phase you’re in, the day of your cycle, how long until your next period is expected, and the messages you send them. It doesn’t show them your daily logs. Don’t share a code with anyone you wouldn’t want seeing that. You can unlink at any time from Profile.
Subscriptions and billing
Soleii is a paid app. It’s $9.99 per month or $39.99 per year, and both plans start with a free trial for new customers. The length of that trial is shown in the app before you subscribe, and it can differ between offers. The prices shown in the app are the ones that apply to you, and they can vary by country.
One subscription covers both people. The person tracking their cycle is the one who buys it, and their linked partner gets access for as long as it stays active. If it lapses, both sides lose the paid features.
Billing runs through Google Play. Your subscription renews automatically at the end of each period unless you cancel at least 24 hours before it ends. We send a reminder before your free trial runs out. You can cancel any time under Subscriptions in Google Play. Cancelling stops the next charge and leaves your access running until the period you’ve paid for is over.
Refunds are handled by Google Play under their policy. We don’t process them ourselves.
Deleting your Soleii account does not cancel your subscription. Only the store can do that, so cancel in Google Play first if you’re leaving.
Soleii is not medical advice
The app estimates cycle phases from what you log, and estimates are wrong sometimes. Soleii isn’t contraception, isn’t a fertility treatment, isn’t a pregnancy test, and isn’t a diagnosis. Don’t make a medical decision on the strength of what the app predicted. If something feels wrong with your body, talk to a qualified professional.
Sunflare alerts your linked partner and nobody else. It isn’t an emergency service, and it won’t reach paramedics, a doctor, or anyone outside your partner link. In an emergency, call your local emergency number.
Acceptable use
Don’t use Soleii to harass, monitor, or pressure anyone. Don’t try to reach another person’s data, break the app, or resell access to it. We can suspend or close accounts that do.
Availability and changes
We work to keep Soleii running, but we can’t promise it’ll be available without interruption. Features can change or be removed as the product develops. If we make a material change to these terms, we’ll update this page and the date at the top.
Liability
Soleii is provided as-is. So far as the law allows, we’re not liable for indirect or consequential loss, or for decisions taken on the basis of what the app predicted.
