These Terms of Use (“Terms”) are the agreement between you and Ferhat Gör, trading as Fernis Labs (sole proprietorship; Tahtakale Mah. Gülfidan Sk. No: 3 İç Kapı No: 1, Avcılar / İstanbul, Türkiye) (“we”, “us”) for the Sinyal mobile app for iOS and Android (“Sinyal” or the “app”). They include the subscription terms and serve as the app’s end-user licence agreement (EULA). By creating an account or using the app you accept these Terms. If you do not agree, please do not use Sinyal.
How we handle personal data is explained in our Privacy Policy.
1. What Sinyal is
Sinyal helps you look at visible facial and body-language cues more carefully. You can:
- analyse the body language in one photo;
- analyse the “compatibility” between two people from two photos or a video of up to 10 seconds;
- learn cues with the in-app dictionary;
- play the Signal Hunt game, finding cues in ready-made photos, and compete in its seasonal ranking; and
- with Pro, use the AI coach and the other Pro features described in section 8.
Analyses are produced by an AI model (Google’s Gemini API) and returned as a structured text report. Before any media is sent for analysis the app asks for your explicit consent.
2. What an analysis can and cannot do
- An analysis is an interpretation of visible signals only, such as posture, facial expression or distance, in a single moment or a short clip.
- It cannot determine with certainty anyone’s intent, emotions, whether they are lying or being deceptive, their personality, their health or how a relationship will turn out.
- AI output can be incomplete or wrong. Context the camera does not see — culture, health, the situation, what happened before — can change the meaning completely.
- Sinyal is not professional advice of any kind: not medical, psychological or therapeutic, legal, or human-resources advice. If you need such help, talk to a qualified professional.
- A “compatibility” result describes how the visible cues between two people might be read. It is not a prediction about your relationship.
You are responsible for how you use a report and for any decision you take. Do not treat a report as evidence about a person.
3. Who can use Sinyal
You must be at least 18 years old and able to enter into a binding contract. Sinyal is not intended for children.
4. Your account
- You can sign in with Google, with Apple (on iPhone and iPad) or with an email address and password. Email accounts must verify their address before using the AI features.
- Give accurate information and keep your sign-in details safe. You are responsible for activity on your account.
- You can delete your account at any time in the app under Settings → Account → Delete account. See Account deletion. Deleting your account does not cancel a subscription (see section 9).
5. Photos, videos and other people’s permission
- Only upload photos and videos that you have the right to use and that every person shown has agreed to share with you for this purpose.
- You keep all rights to your media. You give us permission to transmit and process it, including through our service providers, only as needed to produce the analysis you asked for. We do not store raw photos or videos, and we do not use them for any other purpose.
- You are responsible for the media you submit and for making sure that submitting it is lawful.
- You agree to these rules when you start using Sinyal, and they are explained in the app’s Settings. We cannot verify that you follow them; breaking them breaks these Terms.
- You must not submit a photo or video in which anyone is under 18, even with a parent’s or guardian’s permission. If the AI clearly sees a child, the analysis stops without a report; this check is not age verification and can miss cases, so the responsibility stays with you.
6. Things you must not do
Do not use Sinyal:
- to monitor or keep watch on anyone (surveillance), or to track a partner, employee or anyone else without their knowledge;
- to harass, bully, shame, threaten or intimidate anyone, or to publish a report to embarrass someone;
- to discriminate against anyone, or to profile people based on their appearance, origin, religion, disability, gender, sexual orientation or other protected characteristics;
- to make or support decisions about anyone’s employment, recruitment, credit, insurance, housing, education or access to services;
- with media you do not have the right or the people’s permission to share, or with unlawful, sexually explicit or violent content;
- to break the law or infringe anyone’s rights; or
- to interfere with the service: for example reverse engineering it (except where the law allows), getting around usage limits or paywalls, automating requests, or attacking our systems.
We may suspend or close accounts that break these rules.
7. Signal Hunt and the ranking
Signal Hunt (Sinyal Avı) is a free, optional game in which you try to find body-language cues in ready-made photos. Right answers earn XP. Each calendar month (in UTC) is a new season, and the XP you earn during a season sets your place in a ranking that other players can see. What the ranking shows is explained in the “Signal Hunt and the ranking” section of the Privacy Policy.
Fair play
- Play yourself. Do not use bots, scripts or other automated tools, or a modified app, and do not try to find answers by automated means.
- Do not exploit bugs or loopholes. If you find one, please tell us.
- Do not create more than one account, play on someone else’s account or let someone else play on yours to climb the ranking.
Hunter names
- You choose the hunter name shown in the ranking, and you are responsible for it.
- It must not contain insults, swear words, hate speech, sexual content or anything that infringes other people’s rights.
- It must not impersonate, or suggest a connection with, another person, a brand or Sinyal.
- It must not contain personal or contact details, such as an email address, phone number or social media handle.
- We check names against an automatic word list, but this check does not catch everything, and an unsuitable name remains your responsibility.
If the rules are broken
If we find that these rules have been broken, or a name is reported to us as unsuitable, we may change or hide the hunter name, reset or correct XP and season scores, remove the player from the ranking or restrict their access to the game. For serious or repeated breaches, section 14 also applies. If you see an unsuitable name, please email us.
XP has no monetary value
- XP, streaks, places, medals and season results are in-game indicators only. They have no monetary value and cannot be sold, transferred, or exchanged for money, Pro or any other reward. Signal Hunt does not award cash prizes or other prizes.
- With Pro, lives (owls) refill faster, so Pro subscribers can play more often. The XP an answer earns is calculated by the same rules for everyone.
Changes
We may change the game’s rules, scoring, season length, how the ranking is shown and the questions; correct season results because of a bug or cheating; or withdraw the game entirely (see section 11).
8. Free plan and Pro
Free
- 3 analyses per day. The day is counted in UTC and resets at 00:00 UTC.
- One free full report per account.
Pro
- a higher daily analysis allowance than the free plan, including a daily allowance for video analyses, as shown in the app (daily limits keep the service sustainable and protect it from abuse);
- full reports;
- the AI coach, within a daily message allowance; and
- reopening past reports.
Features and limits may change over time (see section 11). The current offer is always shown in the app before you buy.
9. Subscriptions, renewal, cancellation and refunds
- Plans. Pro is available as a weekly or yearly subscription. The price and billing period are shown in the app and in the store before you confirm the purchase, in your local currency where available.
- Payment. Payment is charged to your Apple ID or Google Play account when you confirm the purchase. We never see your card details.
- Automatic renewal. Subscriptions renew automatically for the same period and at the then-current price unless you cancel at least 24 hours before the end of the current period. Your account is charged for renewal within the 24 hours before the current period ends.
- Cancellation. You can cancel or manage your subscription at any time in your App Store or Google Play account settings (the app’s “Manage subscription” button takes you there). Cancelling stops the next renewal; Pro stays active until the end of the period you have paid for.
- Apple: support.apple.com/en-us/118428
- Google Play: support.google.com/googleplay/answer/7018481
- Deleting your account does not cancel your subscription. Cancel it in the store first.
- Refunds are handled by Apple or Google under their own refund policies. We cannot issue refunds for store purchases ourselves.
- Price changes follow the rules of the store, which will inform you and, where required, ask for your consent.
- Your account. Pro is linked to the Sinyal account you were signed in with when you bought it. You can use “Restore purchases” in the app if Pro does not appear.
- No free trial or introductory price is offered at the moment. If one is offered later, its length, price and when it turns into a paid subscription are shown clearly on the purchase screen.
- Right of withdrawal. Pro is a service delivered electronically as soon as the purchase is confirmed. Under Article 15(1)(ğ) of the Turkish Distance Contracts Regulation there is therefore no right of withdrawal. Refund requests are handled by the store you bought from (Google Play or the App Store) under its own refund policy. Any wider right granted by the mandatory consumer law of the country where you live is not affected.
10. Licence and intellectual property
We give you a personal, non-exclusive, non-transferable, revocable licence to install and use Sinyal on devices you own or control, for your own non-commercial use, in line with these Terms and the rules of the store you downloaded it from. The app, its design, text, dictionary content, Signal Hunt questions and photos, and brand belong to us or our licensors. You may use your reports for your own personal purposes, subject to section 6.
11. Availability, changes and updates
We work to keep Sinyal running, but we do not promise it will always be available or error-free. We may improve, change, limit or withdraw features, and we may deliver updates to the app, including over-the-air updates. Some features depend on third-party services (such as Google Gemini) and may stop working if those services change. If we make a change that significantly reduces a paid feature, we will tell you in advance where reasonably possible.
12. Disclaimers
To the extent permitted by law, Sinyal and all analyses are provided “as is” and “as available”, without any promise that results are accurate, complete or fit for a particular purpose. Nothing in these Terms limits the rights you have as a consumer under mandatory law, including Turkish Law No. 6502 on Consumer Protection or consumer law in your country of residence.
13. Limitation of liability
To the extent permitted by law, we are not liable for indirect or consequential losses, or for decisions you or others make based on a report. Nothing in these Terms excludes or limits liability that cannot be excluded or limited by law, such as liability for intent or gross negligence, or for death or personal injury caused by negligence. Nothing in these Terms removes or limits your statutory rights as a consumer.
14. Ending these Terms
You can stop using Sinyal and delete your account at any time. We may suspend or close your account if you seriously or repeatedly break these Terms or if the law requires it; where appropriate we will tell you why. Sections that by their nature should continue (for example 2, 12, 13 and 16) survive the end of these Terms.
15. Additional terms for the Apple App Store
If you downloaded Sinyal from the Apple App Store, the following also applies:
- These Terms are between you and us only, not Apple. We, not Apple, are solely responsible for Sinyal and its content.
- Your licence is limited to using Sinyal on Apple-branded products that you own or control, as permitted by the Usage Rules in the Apple Media Services Terms and Conditions.
- Apple has no obligation to provide maintenance or support for Sinyal.
- If Sinyal fails to meet any applicable warranty, you may notify Apple and Apple will refund the purchase price (if any) for the app. To the maximum extent permitted by law, Apple has no other warranty obligation for Sinyal.
- We, not Apple, are responsible for addressing any claims relating to Sinyal or your use of it, including product liability claims, claims that it fails to meet legal or regulatory requirements, and consumer protection, privacy or similar claims.
- If a third party claims that Sinyal or your use of it infringes their intellectual property rights, we, not Apple, are responsible for investigating, defending, settling and discharging that claim.
- You confirm that you are not located in a country subject to a U.S. Government embargo or designated as a “terrorist supporting” country, and that you are not on any U.S. Government list of prohibited or restricted parties.
- You must comply with applicable third-party terms (for example your mobile data provider’s) when using Sinyal.
- Apple and its subsidiaries are third-party beneficiaries of these Terms and, once you accept them, Apple may enforce them against you.
16. Governing law and disputes
These Terms are governed by the laws of the Republic of Türkiye, and disputes are subject to the courts and enforcement offices of İstanbul. If you are a consumer, this does not take away the protection of mandatory rules of the country where you live or your right to go to the courts there. Consumers in Türkiye may also apply to Consumer Arbitration Committees or Consumer Courts within the limits set by law. Before starting a formal dispute, please contact us — most problems can be solved by email.
17. Changes to these Terms
We may update these Terms, for example when features or the law change. We will update the date at the top of this page and, for significant changes, tell you in the app before they take effect. If you continue to use Sinyal after the changes take effect, the new Terms apply. If you do not agree, you can stop using Sinyal and delete your account.
