Thenia Terms of Use
Last updated: 6 November 2026
1. Scope and Contracting Parties
1.1 These Terms govern professional use of Thenia, an AI-powered email marketing tool provided by OPTIMAL TRADE E.E. (the “Company”).
1.2 Company details: OPTIMAL TRADE E.E., 19th km Spaton Avenue, 190 04 Spata, Attica, Greece, Greek Tax ID 801579680, Pallini Tax Office, GEMI 159506203000, hello@thenia.io. Application: https://app.thenia.io; website: https://thenia.io.
1.3 The Service is available to businesses only, not consumers. Anyone accepting these Terms warrants authority to bind the Store.
2. Definitions
2.1 “Store” means the business connecting its online store; “Account” means its single account; “Application” means https://app.thenia.io.
2.2 “Direct Sale” means an order meeting Section 6; “Indirect Sale” means a non-chargeable order described in Section 6; “Commission” means compensation for a Direct Sale; “Prepaid Balance” means funds deposited in advance to settle amounts owed.
3. Service Description and Operation
3.1 Thenia acts as an autonomous AI agent, analysing customers and orders, predicting repeat purchase timing and generating automated emails, campaigns and appropriate coupons.
3.2 WooCommerce is currently supported through the “Thenia for WooCommerce” plugin; other platforms may be supported later.
3.3 The Service determines timing, priority, products, coupons and copy using store data and consumer-behaviour research. The Store can enable or disable automations, preview messages, select “Do not send”, and exclude customers. The Store retains responsibility for messages sent.
4. Registration, Connection and Activation
4.1 One Account is permitted per Store. Use requires acceptance of these Terms and plugin connection.
4.2 Before activation, data are imported and free analysis is available. No emails are sent until express activation.
4.3 The Store safeguards credentials, is responsible for Account activity and must promptly report unauthorized access.
5. Store Identity Details
5.1 The Store supplies accurate, current legal name, tax ID, postal address and contact email.
5.2 The plugin retrieves the Store logo, name, address, email and phone from its website. The Store must verify and correct them; they appear in email headers and footers.
5.3 For a new Store without a logo, the first email waits until a logo is uploaded.
6. Sales Attribution and Accrual of Commission
6.1 A Direct Sale is an order where the customer (a) clicked a Thenia email within seven days before ordering or (b) used a Thenia coupon, whether or not any email was clicked or received.
6.2 Recovered abandoned carts qualify as Direct Sales only following a click on the corresponding cart email.
6.3 An Indirect Sale is an order within five days after receipt of an email without a click, provided it does not otherwise qualify as a Direct Sale. It is reported but never charged. Each order is counted once.
6.4 Commission accrues when the order is placed, including cash on delivery and pending payment. Subsequent status changes do not automatically cancel it.
## 6A. Website Information and Estimates
6A.1 Examples, figures and illustrative scenarios presented on the website are provided for information and explanation only and do not constitute a guarantee or promise of any particular commercial outcome. The revenue calculator provides an estimate based on the inputs and assumptions used, not a prediction or assurance of actual sales or revenue.
7. Commission Schedule and Calculation
7.1 There is no fixed recurring fee; all features are available to every Store. Only Direct Sales generate Commission.
7.2 Category-specific rates are set out in the Commission Schedule under Analytics → Commission Schedule in the Application and are accessible before activation.
7.3 Thenia assigns products to categories. Pending classification, the lowest rate among categories of that particular Store applies provisionally.
7.4 The calculation base is the product amount payable after coupon discounts, excluding shipping and other charges. Line-item tax is included only where Store prices include tax. Foreign currencies are converted using the ECB reference rate on the order date.
8. Taxes and Invoices
8.1 Commissions exclude VAT. Greek Stores are charged 24% VAT.
8.2 For businesses in another EU member state with a VIES-verified VAT number, reverse charge applies; for businesses outside the EU, Greek VAT is not charged, subject to applicable rules. An unverified VAT number results in VAT being charged but never prevents payment.
8.3 One consolidated invoice is issued monthly using the Store’s declared legal name, tax ID and address.
9. Payment Methods
9.1 A Store may register a card through Stripe on activation, without an immediate charge. Outstanding Commissions are accumulated and charged in instalments once the unpaid amount reaches a specified charging threshold. Any remaining unpaid amount is charged at the end of each calendar month.
9.2 Alternatively, Stores in Greece only may use a Prepaid Balance funded by card, bank transfer or IRIS, from the minimum amount displayed in the Application. Without a card, funds are required before the first email.
9.3 At zero Prepaid Balance, new emails stop immediately. Commissions arising from emails already sent remain payable and are covered by the next top-up. Unused Prepaid Balance is refunded on Account closure.
9.4 Analytics → Charges lists orders, categories, Commissions, explained card charges and balances. Settings → Billing & invoicing contains card details, billing information and invoices.
9.5 After a failed charge, an email provides a card-update link; retries occur every three days. If payment fails for 14 days from the initial failure, sending stops with an in-app notice and automatically resumes after successful payment.
10. Cancellations, Returns and Commission Credits
10.1 Changing an order to cancelled, refunded or deleted does not automatically remove Commission.
10.2 For orders no more than 45 days old, the Store may request full or partial credit beside the order in the Application without submitting documentary proof.
10.3 A reason is mandatory: customer cancellation, non-delivery, returned products, out-of-stock item, duplicate order, incorrect or test order, or another reason with a short description.
10.4 Requests are approved automatically within limits set by Thenia. Repeated cancellations or requests above the limit may be rejected, leaving Commission due; the Store may request reconsideration from support.
10.5 Approved credits offset future charges only, are never paid in cash and expire upon Account closure. If an order is reinstated, Commission becomes due again and the credit is reversed. Discounts and coupons are not grounds for credit.
11. Discount Coupons
11.1 Coupons are discounts offered by the Store, which bears their costs and consequences.
11.2 The Store is responsible for checking commercial conditions and may stop a proposed message before dispatch.
12. Electronic Messages
12.1 Emails are sent through Thenia infrastructure on thenia.io or thenia.ai subdomains, or without extra charge from a connected Store-owned domain. The sender name is the Store name; replies go to its contact email.
12.2 Footers include Store details, one-click unsubscribe, a privacy-policy link and “Sent with Thenia”.
12.3 By default, customers with email addresses are eligible, excluding unsubscribed addresses, invalid addresses, spam complaints and Store exclusions. This default does not establish legal permission.
12.4 Where a Store has a consent field recording express refusals, it chooses “Only those who agreed” or “Everyone”; the choice is logged. “Everyone” does not legalize prohibited contact; the Store alone bears responsibility for the decision.
12.5 Unsubscription is permanent unless the customer independently signs up again with consent.
13. Store Obligations as Sender
13.1 The Store warrants a lawful basis for each marketing email: consent or the applicable existing-customer exception for similar products under Article 11 of Greek Law 3471/2006 and the GDPR, with an opt-out at collection and in every email.
13.2 The Store informs customers in its privacy policy, obtains cookie consent where required, avoids purchased or borrowed lists and unlawful or misleading content.
13.3 Sender information must be truthful and identified deficiencies promptly corrected.
14. Sending Infrastructure Protection
14.1 The Company monitors bounces and spam reports to protect sending reputation.
14.2 Where provider thresholds are exceeded or risks arise, it may temporarily slow, limit or suspend all or part of a Store’s sending, including particular customer groups, to the necessary extent and duration.
15. Artificial Intelligence
15.1 AI-generated recommendations, discounts and copy may contain errors. The Store can preview and stop messages before sending.
15.2 Only product and category information, never customer personal data, is sent to AI providers. Data are not used to train AI models; providers are contractually required to prohibit such use.
15.3 No sales, performance or business outcome is guaranteed.
16. Availability and Maintenance
16.1 The Company uses reasonable efforts to maintain uninterrupted operation but gives no uptime percentage guarantee.
16.2 Maintenance, updates and emergency interventions may occur, with advance notice where practicable.
17. Suspension
17.1 The Company may suspend access or sending for material breach, non-payment, security risks or unlawful use, with notice where practicable or immediately in emergencies.
17.2 Suspension does not extinguish previously accrued Commissions.
18. Account Closure and Financial Settlement
18.1 The Store may close its Account at any time under Settings → Privacy & data. All outstanding accrued Commissions are charged before closure completes.
18.2 No new Commissions accrue after closure is completed. Amounts already charged are non-refundable, subject to approved credit adjustments under Section 10 and return of unused Prepaid Balance under Section 9. Credits cannot be redeemed for cash and expire on closure.
19. Personal Data and Deletion
19.1 The Store is controller and the Company processor for customer data. The Data Processing Agreement forms part of these Terms. Privacy policy: https://app.thenia.io/privacy.
19.2 The Store may export data at any time under Settings → Privacy & data.
19.3 Data are deleted 90 days after closure, with notices 15 and 5 days beforehand. Never-activated Stores are deleted 30 days after connection, with notice 7 days beforehand. Only hashed suppression records and legally required tax records are retained.
19.4 For its customers' requests concerning their personal data, the Store uses the customer export and erasure tools under Settings → Privacy & data or, where supported, the corresponding WordPress tools. Erasure is carried out as set out in the Data Processing Agreement and is final. Requests received by the Company are forwarded to the Store.
20. Intellectual Property
20.1 Thenia software, marks and content belong to the Company. The Store receives a limited, non-exclusive, non-transferable license for the term of use.
20.2 Store materials remain the Store’s property and are licensed to the Company solely to provide the Service. Reverse engineering is prohibited to the extent permitted by law.
21. Liability and Indemnification
21.1 The Company’s aggregate liability is capped at amounts paid by the Store in the six months preceding the event. Lost profits and indirect damages are excluded.
21.2 These limits do not apply to fraud, wilful misconduct, gross negligence under Article 332 of the Greek Civil Code, or liabilities that cannot lawfully be limited.
21.3 The Store indemnifies the Company against damage from third-party claims caused by the Store’s breaches.
22. Amendments
22.1 Material amendments are notified by email at least 30 days before taking effect; the Store may close its Account beforehand.
22.2 Commission rate or billing-method changes are emailed at least 14 days in advance and apply only to subsequent sales. New Stores are bound upon electronic acceptance.
23. Final Provisions
23.1 Invalidity of any provision does not invalidate the remainder. Failure to exercise a right is not waiver.
23.2 Notices go to the Store’s latest registered email.
23.3 Greek law governs and Athens courts have jurisdiction. The Greek version prevails over any translation.
24. Third-Party Trademarks
24.1 The trademarks “WooCommerce” and “WordPress”, as well as any other third-party trademarks referenced in the Service, are the property of their respective owners, including Automattic Inc. and the WordPress Foundation. Thenia is an independent service and is not affiliated with, partnered with, sponsored by, endorsed by, or otherwise approved by these entities.
