Sola - Terms of Service

Last Updated: 13 August 2026
Effective Date: 13 August 2026


Welcome to Sola!

These Terms of Service (“Terms”) govern your use of the Sola application (“App,” “Service,” or “Sola”), developed and operated by DRNKN, an independent developer (“we,” “us,” or “our”). By downloading, installing, or using Sola, you agree to be bound by these Terms.

Please read these Terms carefully before using the App. If you do not agree to these Terms, do not use Sola.


1. Description of Service

Sola is a period, ovulation and pregnancy tracking app for iPhone that allows you to:

The App works offline. It does not require an account, and there is no login.


2. Eligibility

2.1 Age Requirements

You must be at least 13 years old to use Sola. If you are between 13 and 18 years old (or the age of majority in your jurisdiction), you may only use Sola with the consent and supervision of a parent or legal guardian who agrees to be bound by these Terms.

2.2 No Account Required

Sola does not require account creation. The App uses your device’s local storage and, if you turn on iCloud backup, Apple’s iCloud service. By using iCloud features, you agree to Apple’s terms and conditions.


3. Not Medical Advice

Sola is not a medical device. It does not diagnose, treat, cure, or prevent any condition, and nothing in it is medical advice.


4. Purchases and Payments

4.1 Free Trial

Sola offers a free trial with everything included. The trial length and any renewal terms are shown to you by Apple before you confirm. Unless cancelled before it ends, the trial converts to the plan you selected.

4.2 Plans

Sola is offered as an auto-renewing subscription (monthly or yearly) or as a one-time lifetime purchase. Subscriptions renew automatically until cancelled. The lifetime option is a single payment with nothing to renew and nothing to cancel.

4.3 Read-Only, Never Locked

If your subscription ends, Sola turns read-only. It does not lock.

Your data was never the product, and it is never held hostage against a payment.

4.4 Pricing

Prices are displayed in the App, are set by region, and are shown to you by Apple in your own currency before you confirm. We may change prices in future. A price change never affects a lifetime purchase you have already made, and any change to a subscription price is subject to Apple’s notice and consent rules.

4.5 Billing

4.6 Refunds

Refunds are handled by Apple in accordance with their refund policies. We cannot process refunds directly. To request one, contact Apple Support or visit reportaproblem.apple.com.


5. Your Content

5.1 You Own What You Log

“Your Content” means the cycle data, day logs, notes, and settings you create in the App. You retain full ownership. We claim no licence over it.

Your Content is stored on your phone, and in your own iCloud account if you turned backup on. It is never transmitted to us. We cannot read it, cannot copy it, and cannot use it for training, for promotion, or for anything else, because we never receive it. There is no server of ours holding it, which means there is nothing of yours for us to sell, lose, or be compelled to produce.

5.2 No Lock-In

Settings → Export everything hands you a plain CSV file, made on your phone, at any time and on any tier. If we ever discontinue the App, everything you exported remains readable in any spreadsheet or text editor.

5.3 Backup and Deletion Are Yours to Control

5.4 Acceptable Use

You agree NOT to:


6. Intellectual Property

6.1 Our Property

The App, including its design, features, code, graphics, and branding (excluding Your Content), is owned by us and protected by intellectual property laws. The Sola name, logo, and associated branding are ours.

6.2 Limited Licence

We grant you a limited, non-exclusive, non-transferable, revocable licence to use the App for personal purposes in accordance with these Terms.

6.3 Feedback

If you send us feedback, suggestions, or ideas about the App, you grant us the right to use them without compensation or attribution. Please do not send us your logs or exported files; we do not want a copy.


7. Third-Party Services

7.1 Services We Use

7.2 Third-Party Terms

Your use of third-party services is subject to their own terms and privacy policies. We are not responsible for their practices.


8. Feature Expectations and Disclaimers

8.1 Predictions Are Predictions

Sola predicts from your own history rather than a population average. Early on, with little history, predictions are wide, and Sola says so rather than pretending to precision it does not have. Irregular cycles are not errors and are not flagged as abnormal.

8.2 Reminders Are Best-Effort

Reminders are delivered by iOS. Notification permissions, Focus modes, Low Power Mode, and system scheduling all affect delivery, and we cannot guarantee that a reminder arrives at an exact moment. Reminder text is deliberately vague by design; it will never name what it is about.

8.3 Data Loss

The App saves as you tap and, if you enabled it, backs up to iCloud. Neither is a substitute for your own backups. We are not liable for loss of Your Content, whether caused by device failure, iCloud unavailability, accidental deletion, or a defect in the App. Use Export everything regularly if your history matters to you.


9. Disclaimers and Limitation of Liability

9.1 “As Is” Service

THE APP IS PROVIDED “AS IS” AND “AS AVAILABLE” WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO:

9.2 Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE SHALL NOT BE LIABLE FOR:

9.3 Jurisdictional Variations

Some jurisdictions do not allow the exclusion of certain warranties or limitation of liability. In such jurisdictions, our liability is limited to the maximum extent permitted by law.


10. Indemnification

You agree to indemnify and hold harmless the developer of Sola from any claims, damages, losses, or expenses (including reasonable attorneys’ fees) arising from your use of the App, your violation of these Terms, your violation of any third-party rights, or Your Content.


11. Termination

11.1 By You

You may stop using Sola at any time by deleting the App. Export your data first, because deleting the App removes local data. Deleting the App does not cancel a subscription — do that in your Apple Account settings.

11.2 By Us

We may terminate or suspend your access to the App at any time, with or without cause, with or without notice. Reasons may include violation of these Terms.

11.3 Effect of Termination

Upon termination your licence to use the App ends. Provisions that by their nature should survive, such as intellectual property, disclaimers, and limitations of liability, continue to apply. Your data remains yours, in CSV, wherever you have exported it.


12. Changes to the Service and Terms

12.1 Changes to the App

We may modify, suspend, or discontinue the App or any of its features at any time. If a feature a paid plan relied on is discontinued, we will say so clearly and in advance where we reasonably can. Export will not be one of them.

12.2 Changes to Terms

We may update these Terms from time to time and will notify you of material changes through the App or by other means. Continued use after changes take effect constitutes acceptance.


13. Governing Law and Disputes

13.1 Governing Law

These Terms are governed by the laws of Indonesia, without regard to conflict of law principles.

13.2 Dispute Resolution

Before initiating any legal action, you agree to contact us first and attempt to resolve the dispute informally. Most concerns can be settled quickly by email.

If we cannot resolve a dispute informally, any legal proceedings shall be brought in the courts located in Indonesia, and you consent to the jurisdiction of such courts.

13.3 Class Action Waiver

To the extent permitted by law, you agree to resolve disputes individually and waive the right to participate in class action lawsuits or class-wide arbitration.


14. General Provisions

14.1 Entire Agreement

These Terms constitute the entire agreement between you and us regarding the App and supersede any prior agreements.

14.2 Severability

If any provision is found unenforceable, the remaining provisions continue in effect.

14.3 Waiver

Our failure to enforce any provision does not constitute a waiver of it or of any other provision.

14.4 Assignment

You may not assign or transfer these Terms without our consent. We may assign our rights and obligations without restriction.
