These Terms of Use (the "Terms") form an agreement between you and IE Denis Salaev ("we," "us," or "our") governing your use of the mobile application Sidius (the "App"). By downloading or using the App you agree to these Terms. If you do not agree, do not use the App.
You must be at least 13 years old to use Sidius. If you are under the age of majority where you live, you may use the App only with the involvement of a parent or guardian.
Sidius is an astrology app. From the date, time and place of birth you enter, it computes your natal chart, shows it as a wheel and a table with an interpretation, writes readings for your day, week, month and year, shows your transits, the Moon calendar and your compatibility with the people you add, and lets you chat or talk out loud with an AI astrologer that knows your chart.
3.1 Free Plan: Sidius can be downloaded and used free of charge. Your natal chart and its interpretation, your daily and longer readings, transits, the Moon calendar and compatibility with the people you add are available without a subscription.
3.2 Sidius Pro: Live voice calls with the astrologer, chatting with it, evening check-ins and listening to readings read aloud are available with a Sidius Pro subscription. Voice calls are limited to the voice minutes included in each subscription period (30 minutes a week on the weekly plan, 120 minutes a month on the monthly plan). Sidius Pro is an auto-renewable subscription offered with a weekly period ("Pro Weekly") or a monthly period ("Pro Monthly"). The price and period are shown in the App before you purchase and may vary by country and currency.
3.3 Billing and Automatic Renewal: Subscriptions are purchased through Apple's App Store and charged to your Apple ID account when you confirm the purchase. The subscription renews automatically for the same period and at the same price unless you cancel it at least 24 hours before the end of the current period. Your Apple ID account is charged for the renewal within 24 hours before the end of the current period.
3.4 Managing and Cancelling: You can manage or cancel your subscription at any time in your Apple ID account settings on your device (Settings → your name → Subscriptions). Cancellation takes effect at the end of the current billing period, and you keep Sidius Pro until then. Deleting the App does not cancel your subscription.
3.5 Refunds: Payments are processed by Apple. Refunds are governed by Apple's App Store terms and must be requested from Apple; we are not able to issue refunds directly.
3.6 Price Changes: If we change the price of a subscription, Apple will notify you in advance and, where required, ask for your consent before the new price applies to you.
3.7 Changes to the Free Plan: We may change the free features, the voice minutes or the features included in Sidius Pro, subject to applicable law. Nothing in these Terms obliges us to keep any feature available or free.
Your readings and the astrologer’s replies in chats, check-ins and voice calls are generated by artificial intelligence (OpenAI models reached through OpenRouter, and Google Gemini for voice) from your natal chart, the positions of the planets and what you tell it. They reflect the traditional symbolism of astrology, are offered for entertainment and self-reflection, and may be imprecise or wrong. They are not medical, psychological, legal or financial advice, and nothing in them should be relied on for decisions about health, money, relationships or safety. If you are going through something serious, talk to a qualified professional.
You keep every right you have in what you write or say to the astrologer. You grant us a limited, non-exclusive, royalty-free licence to process your messages, check-ins and voice and store them and their transcripts for one purpose only: holding the conversation, keeping your journal and the astrologer’s memory, as described in the Privacy Policy. We do not publish your conversations, do not show them to other users and do not use them for marketing.
You agree not to:
We may suspend access from a device that breaks these rules.
The App, its design, its text and its name are ours or our licensors'. Planet positions are computed with the Swiss Ephemeris; the positions of the planets are facts and belong to nobody.
The App relies on our servers, which are hosted by Hetzner Online GmbH, is distributed by Apple, uses RevenueCat to validate App Store subscriptions, OpenRouter and OpenAI to write readings and replies, Google Gemini for voice calls and reading aloud and Open-Meteo for city search. We are not responsible for outages or acts of those providers. Apple is not a party to these Terms and has no obligation to furnish maintenance or support for the App. Apple is a third-party beneficiary of these Terms and may enforce them against you.
The App is provided "as is" and "as available", without warranty of any kind, express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, accuracy, and non-infringement. We do not warrant that the App will be uninterrupted, error-free, or that any reading, forecast or reply will be accurate.
To the fullest extent permitted by law, we are not liable for any indirect, incidental, special, consequential or punitive damages, or for any loss of data, arising out of your use of the App. Our total liability for any claim relating to the App is limited to the greater of the amount you paid us for the App (which is zero) or ten United States dollars.
Some jurisdictions do not allow these exclusions, in which case they apply only to the extent permitted.
You agree to indemnify and hold us harmless from any claim arising out of your misuse of the App, your breach of these Terms, or your infringement of anyone's rights through the content you upload.
You may stop using the App at any time by deleting it, and may have your server-side data removed as described in the Privacy Policy. We may suspend or terminate access if you break these Terms. Sections 5, 7, 9, 10 and 11 survive termination.
Our handling of your data is described in the Privacy Policy, which forms part of these Terms.
These Terms are governed by the laws of Georgia, without regard to conflict-of-law rules. Disputes will be brought before the competent courts of Georgia, except where mandatory consumer-protection law in your country of residence gives you the right to bring proceedings elsewhere.
If any provision of these Terms is held unenforceable, the rest remains in force. These Terms, together with the Privacy Policy, are the entire agreement between you and us about the App.
We may update these Terms. The date at the top shows when they last changed. Continuing to use the App after a change means you accept the updated Terms.
