These Terms of Service ("Terms") govern your access to and use of Synthetic Time Series, available at tseriz.com (the "Service"), operated by Zarruk Serrano, a sole proprietorship (enkeltpersonforetak) registered in Norway under organization number 934370651 ("we", "us", "our").
By creating an account, subscribing to, or otherwise using the Service, you agree to be bound by these Terms. If you do not agree, do not use the Service.
Synthetic Time Series generates synthetic time-series data. You describe the signal you need — either by setting generator parameters directly or by describing it in plain language to our AI assistant — and the Service produces data matching that description. Generated data can be downloaded from your browser as CSV, Excel or JSON, or written to an InfluxDB instance that you provide and control. A REST API is available for programmatic access.
The Service does not require you to upload datasets, and we do not ask you to submit your own time-series data in order to generate output. We may add, change, or remove features at any time.
You must be at least 18 years old, or the age of legal majority in your jurisdiction, to use the Service. You are responsible for maintaining the confidentiality of your account credentials and for all activity under your account.
Notify us immediately at [email protected] if you suspect unauthorized use. You agree to provide accurate account and billing information and to keep it up to date. We require email verification before an account becomes fully usable, and we offer two-factor authentication, which we recommend enabling.
The Service offers a free tier with a fixed monthly allowance, paid subscription tiers billed monthly or annually, and an invoiced enterprise tier. Current tiers, allowances and prices are shown on our pricing page. We do not currently offer a free trial: the free tier is available indefinitely and stops when its allowance is exhausted.
Prices are shown in US dollars (USD) and exclude value-added tax. Applicable VAT, including Norwegian MVA, is calculated and added at checkout based on your billing country. Payments are processed by Stripe; we do not store your full payment card details ourselves. By subscribing, you authorize us (via Stripe) to charge your chosen payment method on a recurring basis until you cancel.
Paid subscription tiers include a monthly allowance of AI credits. If you exceed that allowance, additional usage is metered and billed in arrears on your next invoice. Each account has a monthly overage ceiling; once it is reached, further AI-assisted requests are refused rather than billed. You can view your current usage and remaining allowance in the application at any time.
Credit packs are one-off purchases that add AI credits to your account. They are not a subscription and do not renew. Credit packs are consumed after your monthly allowance is exhausted.
Credits purchased in a credit pack expire 24 months after the date of purchase. Expired credits are removed from your balance and are not refunded or reinstated.
You may cancel or change your subscription at any time from the billing section of your account, or through the Stripe customer portal linked from it. You may also email [email protected]. Cancellation takes effect at the end of the current billing period; we do not provide partial-period refunds except as described in Section 4 or where required by law. Metered overage already incurred remains payable.
We may change our prices with at least 30 days' notice. Continued use after a price change takes effect constitutes acceptance of the new price.
If you are a consumer located in the EU/EEA (including Norway), you generally have a 14-day right of withdrawal from a distance contract under the Norwegian Right of Cancellation Act (angrerettloven), which implements the EU Consumer Rights Directive.
However, because the Service provides digital content and services delivered immediately upon subscribing or purchasing, by completing your purchase and confirming access to the Service you expressly request immediate performance and acknowledge that you lose your right of withdrawal once the Service has been fully or partially delivered. This applies to subscriptions and to credit packs alike: a credit pack is treated as delivered once the credits are added to your balance.
If you do not want to waive this right, contact us before activating your subscription or spending purchased credits. Nothing in this section affects any other mandatory consumer rights you may have under applicable law.
You agree not to:
We may suspend or terminate accounts that violate these Terms.
You own the synthetic data you generate through the Service. We claim no ownership of it and place no restrictions on how you use it, whether for research, testing, training, demonstration or commercial purposes.
You also retain ownership of the material you provide to us — your generator configurations, the prompts and descriptions you write, your AI assistant conversations, and any profile picture you upload ("Your Content"). You grant us a limited license to host, process, and transmit Your Content solely as necessary to operate and provide the Service to you. This includes sending the content of your prompts and conversations to our AI provider so the assistant can respond; see our Privacy Policy for details.
If you configure the Service to write to your own InfluxDB instance, you are responsible for that instance, for the credentials you supply, and for having the right to write data to it. We store those credentials encrypted and use them only to perform the exports you request.
The Service, including its software, design, and branding, is owned by us or our licensors and is protected by intellectual property laws. These Terms do not grant you any rights to our trademarks, logos, or branding except as necessary to use the Service as intended. This section does not affect your ownership of generated data under Section 6.
The Service is provided "as is" and "as available" without warranties of any kind, express or implied, including warranties of merchantability, fitness for a particular purpose, or non-infringement. We do not warrant that the Service will be uninterrupted or error-free, or that any synthetic data generated will be suitable for any particular purpose. You are responsible for validating outputs before relying on them.
Synthetic data is generated, not measured. It does not describe any real-world system, event, or person, and it must not be presented or relied upon as genuine observed data.
The AI assistant produces configurations from your description. Like any language model, it can misinterpret a request or produce a configuration that does not match what you intended. Always review the resulting parameters and output before using them.
To the maximum extent permitted by applicable law, we shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits, data, or business opportunities, arising from your use of or inability to use the Service.
Our total liability for any claim arising out of or relating to these Terms or the Service shall not exceed the amount you paid us in the 12 months preceding the claim.
Nothing in these Terms limits liability that cannot be limited under applicable law, including liability for death, personal injury caused by negligence, or fraud.
We may suspend or terminate your access to the Service at any time if you materially breach these Terms, with notice where reasonably practicable. You may stop using the Service and cancel your subscription at any time.
Unused credit-pack credits remain available until they expire under Section 3.2 or until your account is closed, whichever comes first, and are not refunded when an account is closed. If we terminate your account for a material breach of these Terms, unused credits are forfeited. Sections that by their nature should survive termination (in particular Sections 6 to 9 and 12) will survive.
We may update these Terms from time to time. We will notify you of material changes, for example by email or an in-app notice, before they take effect. Continued use of the Service after changes take effect constitutes acceptance of the revised Terms.
These Terms are governed by the laws of Norway, without regard to conflict-of-law principles, except that if you are a consumer resident in the EU/EEA, you also retain the protection of any mandatory consumer-protection provisions of your country of residence. Disputes shall be subject to the non-exclusive jurisdiction of the Norwegian courts, without prejudice to your right as a consumer to bring proceedings in your country of residence.
