These Terms of Service ("Terms") form a binding agreement between you and Georgii Shilovskii, an individual developer ("we", "us", "our"), the developer of the Ovessa application ("Ovessa" or the "App"), contactable at support@shilovskii.dev.
By installing or using the App, you agree to these Terms. If you do not agree, do not install or use Ovessa.
Ovessa is a private PCOS self-tracking app for iPhone, distributed through the App Store. It runs on your device — no account, no cloud copy of your logs, no analytics. Using the tracker requires an auto-renewing subscription (Annual or Monthly) with a free trial for eligible new subscribers, priced in the App Store and billed by Apple. Ovessa is a self-tracking journal, not a medical device: it does not diagnose, treat, or advise on doses, and its cycle estimates must never be used for contraception. Food grades and allergen screening come from third-party databases and can be incomplete or wrong — always read the physical label. All your data lives on your device; we never receive it and cannot recover it. Your data outlives your subscription: if you stop paying you can still view, export, and delete everything, free.
We may update these Terms from time to time. The "Last updated" date above will reflect the current version. Continued use after a change takes effect constitutes acceptance of the revised Terms.
We grant you a personal, non-exclusive, non-transferable, revocable licence to install and use Ovessa on Apple devices you own or control, in accordance with the App Store Usage Rules and these Terms. You may not redistribute, sublicence, rent, lease, or resell Ovessa, nor remove any proprietary notices from it.
Ovessa is a self-tracking journal, not a medical device, and it provides no medical advice, diagnosis, or treatment. Nothing in Ovessa — including cycle-phase estimates, prediction windows, symptom trends, food grades, or the doctor report — is a diagnosis of any condition or a recommendation to take, change, or stop any medication, supplement, diet, or treatment.
Always consult a qualified healthcare professional about your health, and never disregard professional advice because of something Ovessa displayed. Ovessa records what you choose to log; it never suggests a dose. The doctor report exists to be read by a professional, not to replace one.
Cycle-phase estimates and period-prediction windows are statistical estimates over your own logged history. With PCOS they are inherently wide and uncertain — that is the point of the design. They must not be used for contraception, for planning or avoiding pregnancy, or for any other medical decision. Ovessa is not a fertility or conception tool and makes no fertility claims.
Food grades, nutrition figures, and allergen screening are computed from third-party data sources — a product's own label figures as recorded in Open Food Facts, and the public USDA food database — and, for photo scans, from an explicitly-labelled estimate. These sources can be incomplete, out of date, or simply wrong, and package formulations change.
The allergen screen checks what a product's database record declares — it cannot see what is actually in the food. If you have a food allergy or intolerance, always read the physical package label and rely on your own judgment, not on Ovessa. Photo-based portion and nutrition figures are estimates (typically ±20–30 %) and are labelled as such in the app.
Connecting Apple Health is optional and Ovessa works fully without it. You control what Ovessa may read or write, type by type, in the Health app, and the data flows only on your device. You are responsible for the accuracy of data you author into Apple Health. Ovessa's "Delete everything" never purges Apple Health — manage that data in the Health app.
Ovessa stores everything it handles locally on your device. We do not collect, receive, or have access to any of it, and we cannot recover it after device loss, disk failure, software bugs, deletion, or uninstall. You are responsible for your own backups — use the CSV export or your device backup. See the Privacy Policy for full detail.
You agree not to (a) reverse-engineer, decompile, or disassemble Ovessa except as permitted by applicable law or the App Store EULA, (b) circumvent the subscription, the photo-scan rate limits, or the app-integrity checks, (c) use the photo-scan service other than through Ovessa itself, or (d) use Ovessa to violate any law or any person's rights.
Ovessa, its source code, branding, and documentation are owned by us and protected by applicable copyright and trademark laws. Ovessa bundles no third-party SDKs.
Product data displayed from Open Food Facts is available under the Open Database License (ODbL), with attribution rendered in-app on every product card. Data from USDA FoodData Central is a work of the US Government and is in the public domain. The nutritional criteria the PCOS grade applies are published public guidance, cited in-app.
If you send us questions, feedback, suggestions, or bug reports, you agree that we may use them without obligation, attribution, or compensation, for the purpose of operating and improving Ovessa.
We may release updates that add, modify, or remove features. We currently target iOS 26.5 and later; some changes may affect older iOS compatibility. Updates ship through the App Store.
THE APP IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT.
WE DO NOT WARRANT THAT ANY ESTIMATE, PREDICTION WINDOW, FOOD GRADE, ALLERGEN SCREEN, NUTRITION FIGURE, OR ANY OTHER OUTPUT WILL BE ACCURATE OR COMPLETE, OR THAT THE APP OR THE PHOTO-SCAN SERVICE WILL BE UNINTERRUPTED OR ERROR-FREE.
Some jurisdictions do not allow the exclusion of certain warranties, so the above limitations may not apply to you.
TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF DATA OR PROFITS, OR FOR ANY HEALTH OUTCOME, ARISING OUT OF OR IN CONNECTION WITH YOUR USE OF OVESSA, EVEN IF ADVISED OF THE POSSIBILITY. OUR TOTAL CUMULATIVE LIABILITY SHALL NOT EXCEED THE AMOUNT YOU PAID US (THROUGH APPLE) IN THE TWELVE MONTHS PRECEDING THE CLAIM.
Some jurisdictions do not allow the exclusion or limitation of liability for consequential or incidental damages, so the above limitations may not apply to you.
You may stop using Ovessa and cancel your subscription at any time. We may terminate or suspend access if you materially breach these Terms or where required by law. Sections 3 through 12 survive termination.
You and we acknowledge that these Terms are concluded between you and us only, and not with Apple Inc. ("Apple"). We — not Apple — are solely responsible for Ovessa and its content. To the extent these Terms grant rights or remedies inconsistent with the App Store Terms of Service, the App Store Terms control.
Apple and Apple's subsidiaries are third-party beneficiaries of these Terms and, upon your acceptance of these Terms, will have the right (and will be deemed to have accepted the right) to enforce these Terms against you as a third-party beneficiary thereof.
Apple has no obligation to furnish any maintenance and support services with respect to Ovessa. Any claim relating to Ovessa's failure to conform to any applicable warranty may be directed to Apple, and Apple may refund the purchase price (where applicable). To the maximum extent permitted by law, Apple has no other warranty obligation whatsoever with respect to Ovessa.
You represent and warrant that (a) you are not located in a country that is subject to a U.S. government embargo, and (b) you are not listed on any U.S. government list of prohibited or restricted parties.
These Terms are governed by and construed in accordance with the laws of the United Mexican States (Estados Unidos Mexicanos), without regard to its conflict-of-laws principles. The competent courts of Mérida, Yucatán, México shall have exclusive jurisdiction over any dispute arising under these Terms.
Nothing in this section deprives you of the protection of any mandatory consumer-protection rules of the jurisdiction in which you habitually reside.
We may update these Terms; the Last updated date above will reflect the current version. For questions about these Terms, complaints about the App, or any other inquiry, please contact us:
