Terms of Use
These terms are the agreement between you and DEEP NODE STUDİOS YAZILIM VE TEKNOLOJİ LİMİTED ŞİRKETİ (“Kadans”, “we”), a company based in Istanbul, Türkiye. They cover the Kadans mobile app, the usekadans.com website, and the booking pages we host for coaches.
By creating an account or using Kadans, you accept these terms. If you don’t accept them, don’t use the app. How we handle personal data is a separate document — the privacy policy — and it forms part of this agreement.
Who can use Kadans
You need to be old enough to hold your own Apple or Google account, and at least 13 (or the minimum age where you live, if it’s higher). If you’re using Kadans on behalf of a business, you confirm you’re allowed to accept these terms for it.
Your account
You sign in with Apple or Google, or start anonymously. Keep your device and your sign-in credentials secure — anyone who can unlock them can reach your Kadans data. Tell us at info@deepnodestudios.com if you think someone else has got into your account.
An anonymous account lives on the device that made it. If you lose that device, or reinstall without signing in with Apple or Google first, the records in it are gone and we can’t recover them.
What Kadans is — and what it isn’t
Kadans is a record-keeping tool. It tracks lessons you enter, fees you set, and payments you tell it you received. It is not a bank, a payment processor, an escrow service, or an accountant.
- No money moves through Kadans. Every payment between a coach and a student happens outside the app; the app only records that you say it happened.
- The numbers are yours. Balances, debts, earnings and venue costs are calculated from what you enter. We don’t verify them, and they aren’t accounting, tax, or legal advice. Check them before you rely on them.
- Scheduling suggestions are suggestions. Open slots, travel feasibility, and reminders are there to help you decide — the decision, and the lesson, are yours.
If you coach
Your roster is your business record, and you’re responsible for it. That means:
- Recording only information you have the right to record, and keeping it accurate.
- Getting any consent the law where you work requires — including from a parent or guardian before you record a student who is a minor.
- Deciding what goes in a lesson note, and what you share with a student. Shared notes are visible to that student.
- Setting your own fees and collecting them yourself. Anything you agree with a student — price, cancellation charges, refunds — is between the two of you. Kadans records the policy you configure; it doesn’t enforce it and isn’t a party to it.
For those records, you are the data controller and we process them on your behalf, on your instructions, under the privacy policy.
If you’re a student
You see your own lessons, payment status and balance, plus any note your coach chose to share. What you see reflects what your coach recorded — if something looks wrong, take it up with your coach, who can correct it. You can unlink from a coach in the app at any time.
Your public booking link
A coach can turn on a public booking link. While it’s on, anyone holding the URL can see your display name, sport, venue names and open slots, and can ask for a lesson. Treat the link as public: share it where you want to be found, and pause or rotate it in the app whenever you don’t.
- A request is not a booking. Nothing lands on your schedule until you accept it, and no lesson is confirmed for the person who asked until then.
- If you send a request, give your real name and, if you choose to leave one, a phone number that reaches you. What you submit goes to that coach.
Subscriptions and payment
Kadans is a paid app. An active subscription is what unlocks coaching in the app — today that means adding students to your roster and reactivating paused ones. Without one, your existing records stay yours: you can still open them, read them, and export them.
- You buy from the store, not from us. Subscriptions are sold and charged by Apple’s App Store or Google Play, under that store’s terms and with that store’s payment method. We never see your card details.
- It renews until you cancel. Monthly and yearly plans renew automatically at the end of each period, at the price shown when you bought, unless you cancel at least 24 hours before the period ends.
- Free trials. Where the store offers an introductory free trial, it starts when you subscribe and converts to a paid period when it ends. Cancel before it ends and you aren’t charged. A trial is offered once per store account.
- Cancelling and refunds are handled by the store. Manage or cancel your subscription in your Apple or Google account settings — deleting the app doesn’t cancel it. Refunds follow the store’s policy; we can’t issue them ourselves, though we’ll help you ask.
- Price changes. If we change the price, the store will tell you before it takes effect and ask for your consent where its rules require it. You can cancel instead.
- On iOS, your purchase is also governed by Apple’s standard end-user licence agreement. Where it conflicts with these terms for an App Store purchase, it wins.
Fair use
Don’t use Kadans to:
- Break the law, or record data about someone you have no right to.
- Harass anyone, or send abuse through a booking request, a note, or the feedback form.
- Probe, scrape, overload, or work around any limit, gate, or security measure in the app or the API — including the paywall.
- Resell Kadans, or run it as a service for other coaches under your own account.
- Upload anything malicious, or impersonate someone else.
Who owns what
What you record stays yours. You give us only the permission we need to run the service — to store your records, show them to the people you’ve linked, back them up, and produce your export. We don’t sell your content and we don’t use it for advertising.
Kadans itself — the app, the site, the name, and the design — stays ours. These terms don’t give you a licence to copy or rebrand it.
Availability and changes
We work to keep Kadans up, but we don’t promise uninterrupted service. Maintenance, store outages, and things outside our control happen. We may add, change, or remove features as the product develops; if we remove something you rely on, or make a significant change to these terms, we’ll give you reasonable notice first.
Ending things
You can stop using Kadans whenever you like. To close your account, delete it in the app — More → Account if you coach, Profile if you’re a student. It takes your account and the records tied to it with it, and we can’t bring any of it back. Export first if you want a copy. Cancel your subscription in your store account separately: closing a Kadans account doesn’t stop a store charge.
We may suspend or close an account that breaks these terms, or that we must act on by law — with notice where we reasonably can, and immediately where the risk to other people requires it. What happens to your data afterwards is set out in the privacy policy.
No warranty
Kadans is provided “as is”. To the extent the law allows, we don’t warrant that it will be error-free, always available, or fit for a particular purpose, and we don’t warrant the accuracy of anything derived from the data you enter.
Limits on liability
To the extent the law allows, we aren’t liable for lost profits, lost income, lost or corrupted data, or missed lessons, and our total liability for any claim is limited to what you paid us for Kadans in the twelve months before it arose.
Nothing here limits liability that can’t be limited by law — including for fraud, or for death or personal injury caused by negligence. If you use Kadans as a consumer, you keep every mandatory right the law of your country of residence gives you, and nothing in these terms takes it away.
Changes to these terms
We may update these terms as Kadans changes. We’ll update the “Last updated” date above, and for significant changes we’ll give a more visible notice. Continuing to use Kadans after a change means you accept the updated terms.
Law and disputes
These terms are governed by the laws of Türkiye, and the courts and consumer arbitration committees of Istanbul have jurisdiction — except where the law of your country of residence gives you the right to bring a claim locally, which it may.
Most things are easier to fix by asking. Write to us first at info@deepnodestudios.com and we’ll try to sort it out.
