crestlume Terms of Service

Effective date: 27 October 2026

These terms are the agreement between you and us for using crestlume. Please read them. By creating an account or using the app, you accept them. If you do not accept them, do not use crestlume.

Some parts apply only once a feature launches: paid plans, AI credits, the AI agent running through our server, attachments and chat sync. They are marked (when available).

1. Who we are

crestlume is run jointly by Kostiantyn Durlov and Yevhen Hoha, two individuals (not a company) who live in Romania ("we", "us").

• Email: support@crestlume.com

When you buy a paid plan, the seller is our reseller Paddle, and Paddle's terms also apply to the purchase (section 9). Our Paddle seller account is held by Kostiantyn Durlov.

2. What crestlume is

crestlume is a life tracker that works like a game: tasks and goals earn points, habits build streaks, and rewards cost the coins you earn. It runs on the web, on desktop and on Android.

• Local-first: your data lives on your device. You can use the app without an account.
• Sync: with a free account you can sync your data between your devices through our server. How your data is encrypted, and who can read it, is explained in the Privacy Policy. Please read that section before you rely on sync for sensitive information.
• AI agent: an optional chat assistant that can read and change your app data when you ask it to (section 7).

3. Beta

crestlume is currently in public beta. During the beta:

• everything is free;
• features may change, break or be removed, and data loss is possible;
• the AI agent works only with your own OpenRouter key.

Please keep your own backups using the export in Settings, Data. We will give reasonable notice before the beta ends and before any feature you use becomes paid. Nothing you use for free during the beta will be charged without your clear agreement.

4. Who can use crestlume

You must be at least 18 years old to use crestlume. By using it, you confirm that you are.

You may use crestlume for personal purposes and for your own work. If you use it on behalf of an organisation, you confirm you may accept these terms for it.

5. Your account

• Give a real email address you control. We use it for sign-in and security codes.
• Keep your password, and your Extra privacy passphrase if you use one, to yourself. You are responsible for what happens in your account unless it is caused by our fault.
• One account is for one person.
• If you use Extra privacy and forget your passphrase, we cannot recover your synced data. This is how that mode is designed.
• Tell us at support@crestlume.com if you think someone else has access to your account.

You can delete your account at any time (section 13).

6. Your content

"Your content" means everything you put into crestlume: tasks, goals, notes, habits, messages to the agent, attachments and so on.

• It is yours. We claim no ownership of it.
• Licence to us: you allow us to store, copy, encrypt, transmit and process your content only as needed to run crestlume for you: for example, to sync it between your devices; when you use the agent, to send it to the AI service and model that answers you; and when you report an answer, to read and keep the report. This licence ends when you delete the content or your account, except for copies that remain as described in the Privacy Policy.
• You are responsible for your content and must have the right to use it. If you add information about other people, make sure you are allowed to.
• If you send us feedback or ideas, we may use them freely, without paying you or naming you.

7. The AI agent

7.1 How it works

The agent sends your messages and relevant app data to an AI model through OpenRouter, and can create, change or delete items in your app when you ask. What leaves your device, and where it goes, is explained in section 7 of the Privacy Policy.

• With your own OpenRouter key (the only option during the beta): you use your own OpenRouter account. OpenRouter's terms, its pricing and the policy of the model provider apply to your requests, and OpenRouter bills you directly. The app's default model is a paid one, so using it costs money on your OpenRouter account; free models are marked in the model list. We are not a party to that relationship.
• Through our server (when available): we pass your requests to OpenRouter under our account, and usage counts against your credits (section 10). We choose which models are offered and may change them at any time.

7.2 AI answers can be wrong

AI models make mistakes. They can give incorrect, incomplete or outdated answers, misunderstand you, or take an action you did not intend.

• Check what the agent says and does. Review changes it makes to your data. Keep backups.
• The agent is a productivity helper. It is not a doctor, therapist, lawyer or financial adviser, and its answers are not professional advice. Do not rely on it for decisions about your health, safety, money or legal matters. In an emergency, contact local emergency services.
• Answers are generated by third-party models. We do not review them before you see them and do not control their content.

You can report a bad answer with the "Report" button in the chat or by email. What a report contains, and that it is not end-to-end encrypted, is explained in section 4.4 of the Privacy Policy.

7.3 What you must not do with the agent

In addition to section 8, you must not use the agent to:

• create content that is illegal, sexually exploits or endangers children, promotes violence or terrorism, harasses or threatens people, or infringes others' rights;
• get help with weapons, malware, hacking, fraud, or other harmful or illegal activity;
• try to get around the safety measures of the models or providers ("jailbreaking"), or break the usage policies of OpenRouter or the model provider;
• process other people's personal data without a legal right to do so, or make decisions about other people (for example in hiring, credit or housing);
• produce content meant to deceive people, such as spam or impersonation;
• (when available) use our server as a general AI service: for example, calling it from scripts or other apps, sharing or reselling access, sending requests that have nothing to do with your crestlume data, or trying to get around credit limits.

8. Acceptable use

You must not:

• break the law or help anyone else do so through crestlume;
• try to access other people's accounts or data, or our systems beyond what the app offers you;
• probe, scan or test our systems for weaknesses without our written permission (if you find a security problem, please tell us at support@crestlume.com);
• overload, disrupt or interfere with the service, or use bots or automated sign-ups;
• copy, modify, resell or redistribute the app, or reverse engineer it, except as the law allows or an open-source licence permits for that component;
• use crestlume to store or spread malware or illegal content.

9. Paid plans and Paddle (when available)

9.1 Plans

crestlume will have a free plan and a paid subscription, Pro. Regular sync stays free for everyone. Pro adds sync of your agent chats and a larger AI credit allowance (section 10). The exact features, prices and allowances are shown on our website and at checkout before you pay.

9.2 Paddle is our reseller

Our order process is conducted by our online reseller Paddle.com. Paddle.com is the Merchant of Record for all our orders. Paddle provides all customer service inquiries and handles returns.

In practice: Paddle sells you the subscription, takes your payment, calculates and collects taxes such as VAT, issues your invoices and processes refunds. Depending on where you buy, the reseller is Paddle.com Inc. (USA), Paddle.com (Canada) Ltd. (Canada) or, everywhere else, Paddle.com Market Limited (England and Wales). Paddle's Buyer Terms apply to your purchase alongside these terms. We provide the crestlume service itself, and you can always write to us at support@crestlume.com about it.

9.3 Prices and taxes

The price, billing period and any taxes are shown at checkout before you pay. Your bank may add its own fees, for example for currency conversion.

9.4 Renewal and cancellation

• Subscriptions renew automatically at the end of each billing period until you cancel.
• You can cancel at any time: use the link in your Paddle receipt email, Paddle's buyer portal at paddle.net, or write to us.
• When you cancel, Pro stays active until the end of the period you have paid for. Then your account moves to the free plan. Your data stays; only the Pro features stop. Synced agent chats then stop syncing, but chats already on your devices stay there.

9.5 Price changes

We may change prices for future periods. We will tell you by email at least 30 days before a new price applies to you. If you do not agree, cancel before the change takes effect.

9.6 One account, every platform

Pro works on every platform once you sign in with the same account, wherever you bought it.

10. AI credits (when available)

When the agent runs through our server, each request uses credits. Credits are our simple unit for AI usage; how many a request uses depends on the model and the length of the conversation.

• Every account gets a credit allowance per period. Pro has a larger one. The current allowances are shown on our website and in the app.
• The period is the calendar month on the free plan and your billing period on Pro.
• Credits are an allowance, not a balance: they cannot be bought separately or topped up, unused credits do not carry over to the next period, and they have no cash value. They cannot be transferred, exchanged or refunded on their own.
• When you run out, the agent through our server stops until the next period starts. You can still use your own OpenRouter key.
• We may change which models are available and how many credits they use, for example when providers change their prices. We will not reduce the Pro allowance during a billing period you have already paid for.
• To keep the service fair and affordable, we may apply limits such as a daily cap or a maximum request size, and we may require a verified email.

11. Refunds and your right of withdrawal

Our Refund Policy explains refunds. In short: you can get a full refund within 14 days of the first payment of a subscription, without giving a reason. This covers the right of withdrawal that consumers in the EU and the UK have for online purchases. Refunds are processed by Paddle.

12. Changes to crestlume

We keep improving crestlume and may add, change or remove features. If we remove or substantially reduce a paid feature you are paying for, we will tell you in advance and you may cancel; if the change is to your disadvantage and not minor, you may also get a refund for the unused part of your period. This does not limit your rights under section 15.

If we decide to shut crestlume down, we will give at least 30 days' notice, keep the export available so you can take your data with you, and refund any prepaid period that remains unused.

13. Ending this agreement

• You can stop using crestlume at any time and delete your account in the app (Settings, Sync, Delete account), on app.crestlume.com/delete-account, or by email. Deleting your account does not by itself cancel a Pro subscription; cancel it first (section 9.4), or ask us to do both.
• We may suspend or close your account if you seriously or repeatedly break these terms, if the law requires it, or to protect other users or the service. Where possible and lawful, we will warn you first, explain why and give you a chance to export your data. If we close your account without you having broken these terms, we will refund the unused part of any prepaid period.

Sections 6 (feedback), 15, 16 and 17 continue to apply after the agreement ends.

14. Other services

crestlume works with services run by others, such as OpenRouter and AI model providers, Google Calendar and Paddle. Their own terms apply to your use of them. We are not responsible for how they run their services, but we choose them carefully and describe what they receive in the Privacy Policy.

The crestlume app, its design and its name belong to us. The app includes open-source components, which are used under their own licences.

15. Our responsibility for the service

If you are a consumer in the EU, you have a legal guarantee that the service, including paid features, matches what we described and works as it should. If it does not, you can ask us to fix it, and in some cases get a price reduction or end the contract. Nothing in these terms limits that guarantee or any other rights you have under the consumer law of the country where you live.

Beyond those rights, crestlume is provided "as is". In particular, we do not promise that the service will be uninterrupted or error-free, that sync will never lose data, or that AI answers will be correct.

16. Liability

• We are fully liable for damage we cause intentionally or through gross negligence, for death or personal injury caused by our negligence, and wherever the law does not allow liability to be limited.
• For other damage caused by ordinary negligence, we are liable only for damage that was typical and foreseeable when you started using the relevant feature. To the extent the law allows, our total liability in that case is limited to the amount you paid us in the 12 months before the event, or EUR 50 if that is more.
• We are not liable for loss caused by things outside our reasonable control, by services of third parties we do not control, or by your own actions, such as losing your passphrase, not keeping backups, or applying changes the AI agent suggested.

Nothing in this section limits your mandatory rights as a consumer.

17. Governing law and disputes

These terms are governed by the law of Romania. If you are a consumer, you also keep the protection of the mandatory consumer laws of the country where you live, and you can bring a claim in the courts of that country. We can only bring a claim against a consumer in the courts of the country where the consumer lives.

If something goes wrong, please write to support@crestlume.com first. We will try to solve it with you quickly. You may also use an alternative dispute resolution body in your country, where one is available.

18. Changes to these terms

We may update these terms, for example when paid plans launch. For important changes we will tell you in the app or by email at least 30 days before they take effect. If you do not agree, you can stop using crestlume and delete your account, and if you have a Pro subscription, cancel it before the change applies to you. Continuing to use crestlume after the change takes effect means you accept the new terms.

19. General

• If a part of these terms is found invalid, the rest still applies.
• If we do not enforce a right straight away, we do not give it up.
• We may transfer this agreement to a company we set up to run crestlume, or to someone who takes over crestlume, if your rights are not reduced. We will tell you beforehand. You may not transfer your account.
• These terms, the Privacy Policy and the Refund Policy are the whole agreement between you and us about crestlume.
• These terms are written in English. If we provide a translation and it differs, the English version applies, unless the law where you live says otherwise.
