Terms of Use

By using the Telos mobile app and the web interface at telos.onl (together, "Telos") you accept these terms. If you do not accept them, please do not use the app.

How we handle your data is described separately in our Privacy Policy, which forms part of these terms.

• You must be at least 13 years old to use Telos. If you are under 18, you should use the account with the consent of a parent or guardian.
• You provide a valid email address when you sign up. You are responsible for keeping your password safe and for activity on your account.
• Tell us if you notice unauthorised use of your account.
• You can delete your account from inside the app at any time. The deletion flow and the 30-day recovery window are described in the Privacy Policy.

We grant you a limited, non-exclusive, non-transferable and revocable licence to use Telos for your own personal, non-commercial purposes. The app itself (its code, design, copy and visual language, including the orb) remains ours.

You must not:

• copy, sell, rent or redistribute the app;
• attempt to access the source code, reverse engineer the app, or work around its security measures;
• overload the service with automated tools, or try to access other people's data.

The core of Telos is free. Adding new entries in some modules and certain advanced features are unlocked with a Telos Premium subscription. Its terms are:

• Length and price: Premium is offered monthly or yearly. The current price is shown clearly before purchase, both on the subscription screen in the app and in the App Store / Google Play. Prices may vary by country according to each store's currency and tax rules.
• Automatic renewal: The subscription renews automatically. Unless you cancel at least 24 hours before the end of the current period, you will be charged again for another period of the same length.
• Payment: You are charged through your App Store or Google Play account when the purchase is confirmed. Renewal charges are taken within the 24 hours before the current period ends.
• Managing it: You can manage your subscription and turn off automatic renewal in your App Store account settings (iOS) or under Google Play › Subscriptions (Android).
• Price changes:If we change the price, you will be notified as required by the store's rules and given the chance to cancel before the next renewal.
• Restoring purchases: If you change device or reinstall the app, use "Restore purchases" on the subscription screen to recover a subscription bought with the same store account.

A 7-day free trial may be offered the first time you subscribe to Premium. The trial is available once per account.

• Unless you cancel at least 24 hours before the trial ends, it converts automatically into a paid subscription and the price of your chosen plan is charged.
• You are charged nothing if you cancel during the trial.
• If you buy a subscription before the trial ends, any unused part of the trial is forfeited.

When you cancel, Premium stays active until the end of the period you have already paid for; it does not disappear immediately. After that your account returns to the free version. Your data is not deleted; you simply cannot add new entries in premium modules.

Because payments are taken by the App Store and Google Play, refunds follow those stores' policies. On iOS you request a refund from Apple at reportaproblem.apple.com; on Android you request it from Google through Google Play. Any statutory withdrawal or refund rights you have as a consumer, for example under Turkish or European Union consumer law, remain unaffected.

From time to time we may grant an account time-limited Premium access manually, without a store purchase. Such access is a gift: it creates no purchased entitlement, cannot be transferred or exchanged for money, and ends automatically when its period expires.

Telos is meant to be a calm place. Please do not:

• post unlawful, threatening, harassing or hateful content;
• share someone else's personal data without their consent;
• upload or share content that infringes someone else's intellectual property;
• impersonate another person or organisation;
• abuse the service: spam, automated account creation, security testing, excessive request load.

Everything you put into Telos (your habits, notes, journal entries, goals, finance and fitness data) belongs to you. We claim no ownership over it.

We hold only the limited permission needed to provide the service to you (storing it, delivering it to your devices, processing it in the features you switch on). That permission ends when you delete your account.

If you choose to share a habit pack or a list with the Community, what you share (the pack name, its description and the names of the habits inside it) becomes visible to other users. Your logs, streaks and statistics are never shared.

Shared packs are reviewed before they go live. We may take down a submission that breaches these terms, and you can withdraw your own submission at any time.

The Guide (monthly report), photo-based macro estimation and similar features use AI models. Their output is an estimate and can be wrong. The numbers are an approximation, not a measurement; use your own judgement before acting on them.

A monthly usage limit applies so AI features stay fair for everyone. Which data enters this flow (and that your journal text does not by default) is described in the Privacy Policy.

Telos is not a health, nutrition, fitness or financial adviser. Calorie and macro estimates, training plans, quit counters, spending summaries and AI commentary are for information and personal tracking only.

If you have a health condition, dietary restriction, are pregnant, are working through an addiction, or are about to make a significant financial decision, please consult a qualified professional. Telos never diagnoses, never prescribes treatment and never gives investment advice.

We keep developing Telos: features may be added, changed or removed. If we significantly restrict or remove a paid feature, we will let you know.

The service may be temporarily unavailable because of maintenance, infrastructure problems, or outages at third-party providers (Supabase, Apple, Google, AI providers). We cannot guarantee uninterrupted operation.

Telos is provided "as is". To the extent permitted by applicable law, we make no express or implied warranty that the app will be uninterrupted, error-free, or fit for a particular purpose.

Again to the extent permitted by applicable law, we are not liable for indirect, incidental or consequential damages. In any case our total liability is limited to the amount you paid for Telos in the 12 months before the claim arose.

This section does not affect the statutory rights you have as a consumer that cannot be limited by contract.

You can delete your account at any time. We may suspend or close an account that seriously breaches these terms, and we will warn you first where we reasonably can. What happens to your data after closure is described in the Privacy Policy.

If you downloaded Telos from the Apple App Store, the following also applies. These clauses satisfy the minimum terms of Apple's standard licence agreement.

• Parties: This agreement is between you and Ahmet Mert Dinçer, not Apple. We alone are responsible for the app and its content.
• Scope of licence: Your licence is to use the app on any Apple-branded product that you own or control, and is subject to the Usage Rules in the App Store Terms of Service.
• Maintenance and support: We are solely responsible for maintenance and support; Apple has no obligation whatsoever in this respect.
• Warranty: If the app fails to conform to any applicable warranty, you may notify Apple and Apple may refund the purchase price. To the maximum extent permitted by law, Apple has no other warranty obligation; any other claims, losses and costs relating to a warranty are our responsibility.
• Product claims: We, not Apple, are responsible for addressing claims relating to the app, including product liability and consumer-protection compliance.
• Intellectual property:If a third party claims the app infringes their intellectual property rights, investigating, defending and resolving that claim is our responsibility, not Apple's.
• Legal compliance: By using the app you represent that you are not located in a country subject to a U.S. Government embargo and that you are not on any U.S. Government list of prohibited or restricted parties.
• Third-party beneficiary: Apple and its subsidiaries are third-party beneficiaries of this agreement and have the right to enforce it against you.
• Developer: Ahmet Mert Dinçer, Köşk Mah. Sazay Sok. No: 1/5, Keçiören / Ankara, Türkiye.
• Contact: For any question, complaint or claim about the app, write to support@telos.onl.

If you downloaded Telos from Google Play, the Google Play Terms of Service also apply. Purchases, renewals and refunds are handled through Google Play; Google is not a party to this agreement and is not responsible for the app's content.

These terms are governed by the laws of the Republic of Türkiye, and the courts of Türkiye have jurisdiction over disputes. If you are a consumer, you keep the rights granted by the law of your own country that cannot be limited by contract, including the right to bring proceedings before your local consumer courts.

We may update these terms from time to time. Changes are published on this page and the "last updated" date above is refreshed. If a change is significant we will tell you inside the app. Continuing to use Telos after a change means you accept the updated terms.

If you have questions about these terms, write to us at support@telos.onl.
