These Terms of Service ("Terms") govern your access to and use of OreML, downloadable software (Windows and Linux) for zero-code tabular data preprocessing (the "Software"), together with any related updates, licence services, and this website (collectively, the "Service"). By purchasing, downloading, installing, or using the Software, you agree to be bound by these Terms. If you do not agree, do not use the Service.
The Software is developed and provided by the operator of OreML, a sole proprietorship based in Greece ("we", "us", "OreML", the "Licensor") — [OPERATOR DETAILS — PENDING REGISTRATION: registered name, ΑΦΜ (tax identification number), and registered address will be inserted here once the business registration is complete]. Billing, invoicing, and payment collection for the Service are handled by our authorized reseller, Paddle (see Section 4 below).
OreML processes tabular datasets (CSV, Parquet, Excel, and similar formats). Each purchased licence is issued as a single node-locked key, bound to one device at a time (see Section 5).
All purchases of OreML are sold by and billed through Paddle.com Market Ltd ("Paddle"), acting as our authorized reseller and the Merchant of Record for this transaction. Paddle is responsible for processing your payment, calculating and remitting applicable VAT/sales tax, issuing invoices and receipts, handling cancellations, and processing refunds. Your purchase is subject to Paddle's own Buyer Terms and Refund Policy, in addition to these Terms. For anything related to your payment, invoice, VAT, subscription cancellation, or refund, Paddle — not OreML — is your contracting party for that transaction and the correct point of contact (see our Refund Policy).
Subject to your compliance with these Terms and payment of applicable fees, we grant you a limited, non-exclusive, non-transferable, revocable licence to install and use one copy of the Software on one machine at a time, for your own internal data-processing purposes.
You may not: (a) reverse-engineer, decompile, or disassemble the Software, except to the extent such restriction is prohibited by applicable law; (b) circumvent or attempt to circumvent any licence-key validation, machine-binding, or usage-limit mechanism; (c) resell, sublicense, rent, lease, or distribute the Software or your licence key to any third party; (d) remove or obscure any proprietary notices; or (e) use the Software to build a competing product.
The Software, including its underlying methodology and all associated intellectual property, remains the sole property of the Licensor. No ownership rights are transferred to you — only the licence described in this section.
Your licence is bound to one machine at a time. The in-app "Deactivate this machine" option (Settings → Licence) immediately frees your seat so the licence can be activated on a different computer. This is intended for migrating your licence — for example, when you get a new computer, reinstall your operating system, or replace hardware — and not for switching back and forth between two machines you use side by side. If you regularly need OreML active on two machines at the same time, please purchase a second seat rather than transferring repeatedly between them.
To keep this migration path from being used to share one seat across many machines, activating your licence on a machine it has not been active on before (a "transfer") is limited to two transfers in any rolling 180-day period. "Rolling" means we always look back 180 days from the moment of the request, not a fixed calendar period that resets on a set date — an older transfer simply ages out of that window over time. Re-activating a machine your licence has already been active on is always free and does not count against this limit. If you reach the limit, the Software will tell you the date on which your oldest transfer ages out and a transfer becomes available again.
If your machine is lost, stolen, or has failed and you cannot deactivate it yourself before activating a replacement, contact support@oreml.com for a manual override.
Files you export from the Software in Parquet or Feather format carry a persistent, one-way identifier embedded in the file's own metadata — never in a cell, column, or row of your data. This identifier identifies your licence, not you as an individual; cannot be reversed to recover your licence key or any personal information; and survives ordinary downstream processing (re-saving, selecting columns, filtering rows, joining, reordering), so a file built from your export and forwarded to a colleague or client still carries it. Exports in CSV, JSON, and other formats without a file-metadata layer are not marked.
This does not conflict with our commitment that your data never leaves your machine while the Software runs (Section 3): the identifier is never transmitted to us or to anyone else by the Software. It exists solely inside the files on your own device, and travels only if and where you choose to send those files yourself. See our Privacy Policy for further detail.
We offer a free, cardless trial: no payment card is required to start. The trial is limited to one dataset of up to 100,000 rows, 100 columns, and 250 MB, for a single processing run, for 8 days from the day you start the trial. All 25 processing steps run at full capability on data within this cap. If you do not add a payment method before the trial period ends, the trial simply lapses — you are never charged.
The paid subscription is $49 per month plus applicable VAT/sales tax, calculated by Paddle at checkout based on your location. Subscribing removes the trial's limits entirely — any dataset size, any number of processing runs, with no time limit.
The subscription renews automatically every month and continues until you cancel — there is no fixed term, and no notice beyond your ordinary billing receipt precedes each renewal. Fees are billed in advance on a recurring monthly basis by Paddle until cancelled. You can cancel at any time, at least as easily as you signed up, through Paddle's Buyer Portal at paddle.net, or from within the app under Settings → Licence. Cancelling stops future renewal charges; your access continues until the end of the billing period already paid for (see our Refund Policy for how refunds and your statutory withdrawal right work).
Cancelling your billing subscription is separate from deactivating a machine seat: cancelling stops future charges (your access continues until the end of the current billing period, then locks); deactivating a machine frees that seat so the licence can be activated on a different computer (see Section 6), without affecting your billing.
By subscribing, you expressly request that we begin supplying the Service to you immediately, before the 14-day statutory withdrawal period described in our Refund Policy has run. Requesting immediate access does not reduce your withdrawal right — see Section 5 of our Refund Policy for how immediate access and your full withdrawal right sit together.
Your licence is revocable. If your subscription is cancelled, a payment fails and is not resolved, or we revoke a licence for breach of these Terms (including attempted circumvention of licence protections), the Software will gracefully lock: it will refuse to run its licensed functionality, but it will never delete, corrupt, or modify any of your data or files. Reactivating a valid, paid licence restores full functionality immediately.
The Software is provided "as is" and "as available," without warranty of any kind, express or implied, including without limitation warranties of merchantability, fitness for a particular purpose, and non-infringement.
The Software applies automated statistical, machine-learning, and data-transformation techniques to your data. Its outputs, recommendations, and any derived models are provided for informational purposes only and do not constitute professional, financial, medical, legal, or other advice. We do not warrant the accuracy, completeness, or fitness of any output for your specific use case. You remain solely responsible for validating results before relying on them for any decision.
To the maximum extent permitted by applicable law, in no event will the Licensor be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits, revenue, data, or business opportunity, arising out of or related to your use of the Software, even if advised of the possibility of such damages. Our total aggregate liability for any claim arising out of or relating to the Service will not exceed the amount you paid for the Service in the twelve (12) months preceding the claim. Nothing in these Terms limits liability that cannot be limited under applicable EU or Greek consumer-protection law.
You agree to use the Software only for lawful purposes and in compliance with all applicable export-control and sanctions laws. You may not use the Software in any jurisdiction subject to comprehensive trade sanctions, or if you are a restricted or denied party under applicable law.
These Terms are governed by the laws of Greece and, where applicable, European Union law, without regard to conflict-of-law principles. If you are a consumer resident in the EU or UK, nothing in these Terms affects the mandatory statutory rights available to you under the law of your country of residence, including applicable withdrawal rights (see our Refund Policy).
The Software incorporates open-source and other third-party components. Where their licences require it, their copyright and licence notices are reproduced at Third-Party Notices, which forms part of these Terms by reference.
We may update these Terms from time to time. Material changes will be reflected by an updated "Last updated" date above. Continued use of the Service after changes take effect constitutes acceptance of the revised Terms.
Questions about these Terms can be sent to support@oreml.com. For billing, invoicing, or refund matters, please see Paddle's Buyer Terms or our Refund Policy.
