Terms of Service

Acceptance

By using turingdna.com, the directed-evolution engine, the synthesis ordering features (when available), our APIs, or any other product or service we make available (together, the "Service"), you agree to these Terms and to our Privacy Policy. If you do not agree, do not use the Service.

You must be at least 18 years old and legally able to form a binding contract. The Service is not intended for minors. If you accept these Terms on behalf of an organization, you represent you are authorized to bind it, and "you" includes that organization.

What the Service does

The Service is a computational protein-engineering tool that:

• Accepts a wild-type protein sequence (FASTA, GenBank, SnapGene, or raw input).
• Scores position-by-substitution variants using ESM-2 protein language models and assembles optimized variant combinations via simulated annealing.
• Returns codon-optimized DNA, primer pairs, suggested PCR conditions, and related design artifacts.
• (When available) Lets you order synthesized DNA through participating third-party vendors — the "Marketplace", see §7.

The Service is for research and discovery purposes only. See §12.

Engine outputs are computational predictions

Engine outputs — variant rankings, predicted-fitness scores, codon-optimized DNA, primer pairs, PCR conditions — are statistical predictions generated by machine-learning models trained on public protein-sequence data and refined using aggregated, de-identified signals from use of the Service (see "Your content and your sequences" and the Privacy Policy). They are not experimental measurements of function, expression, stability, or activity. You must independently verify any sequence experimentally before relying on it for any purpose. We make no representation that any designed variant will express, fold, exhibit any predicted property, or be free of off-target effects.

Accounts

To use certain features (including the Marketplace), you must create an account. You agree to:

• Provide accurate, current, complete information and keep it up to date.
• Keep your credentials confidential and not share your account.
• Notify us promptly at info@turingdna.com of any unauthorized use.
• Be responsible for all activity under your account.

We may suspend or terminate accounts that violate these Terms, that we reasonably believe pose a security or compliance risk, or that have been inactive for an extended period (we will send notice before deleting an inactive account).

Acceptable Use

You agree not to, and not to assist anyone else to:

1. Design, order, request, or attempt to synthesize any sequence encoding (in whole or substantially in part) a select agent or toxin listed under 7 CFR Part 331, 9 CFR Part 121, 42 CFR Part 73, the Australia Group control lists, the U.S. HHS Screening Framework Guidance, or comparable laws of your jurisdiction; any pathogen of pandemic potential; any gain-of-function modification of a pathogen; any sequence on a vendor's screening blocklist; or any sequence intended for use as a biological weapon.
2. Use the Service for any clinical, diagnostic, therapeutic, prophylactic, food, feed, or cosmetic purpose, or in any product intended for human or animal consumption or in vivo use.
3. Use the Service to design sequences for gene drives, horizontal-transfer systems, or for environmental release, except in jurisdictions where you hold all required regulatory authorizations and have provided proof on request.
4. Violate any export control or sanctions law, including the U.S. Export Administration Regulations (EAR), International Traffic in Arms Regulations (ITAR), Office of Foreign Assets Control (OFAC) sanctions, EU Dual-Use Regulation 2021/821, or comparable laws. You may not access the Service from, or order synthesis to, Cuba, Iran, North Korea, Syria, or the Crimea / Donetsk / Luhansk / Zaporizhzhia / Kherson regions of Ukraine, or any other country or party subject to comprehensive U.S. sanctions as updated from time to time. You may not be a person or entity on the OFAC Specially Designated Nationals list, the U.S. Commerce Department Entity List, or any equivalent restricted-party list.
5. Reverse engineer, decompile, scrape (other than via published APIs under their terms), or attempt to derive source code, model weights, or training data.
6. Use the Service to train a competing protein language model, foundation model, or directed-evolution system, including by extracting model outputs at scale for that purpose.
7. Interfere with, overload, or disrupt the Service or attempt to gain unauthorized access to any system or data.
8. Misrepresent your identity, affiliation, or authority, or use another person's account.
9. Use the Service in any way that violates applicable law in your jurisdiction or the jurisdiction where the synthesized DNA will be received.

We may investigate suspected violations, refuse orders, suspend access, and report violations to law enforcement, vendors, or biosecurity authorities. See Biosecurity Policy.

Your content and your sequences

You retain all rights in the protein sequences, DNA sequences, designs, and other inputs you submit ("Your Inputs") and in the design outputs the engine generates from them ("Your Outputs", together "Your Content").

You grant TuringDNA a limited, worldwide, non-exclusive, royalty-free license to host, process, transmit, and display Your Content solely to operate the Service for you — including running the engine, returning results, fulfilling synthesis orders you place, and providing support.

Aggregated, de-identified data. You also grant TuringDNA a worldwide, perpetual, irrevocable, royalty-free license to create aggregated, de-identified data derived from Your Content and your use of the Service, and to use that aggregated data to operate, improve, and develop the Service and the models behind it. Aggregated, de-identified data does not identify you and is created and held so that it cannot be used to single out, reconstruct, or reproduce Your individual Content; once in this form it is no longer Your Content or personal data. See Privacy Policy ("Submitted to the engine").

We will not:

• Use Your individual Content — in isolation or verbatim — to train or fine-tune any machine-learning model, or expose it to other users. (We do create and use aggregated, de-identified data as described above.)
• Sell, license, or share Your Content with third parties except as strictly necessary to fulfill orders you place (e.g., transmitting a sequence to the synthesis vendor you select).
• Retain Your Content longer than necessary for the purposes above and as described in the Privacy Policy.

You represent and warrant that you have all rights necessary to submit Your Inputs and to grant the license in this section, and that Your Content does not infringe any third-party right (including patent rights covering specific sequences).

Feedback

If you send us suggestions, ideas, bug reports, or other feedback about the Service ("Feedback"), you grant us a perpetual, irrevocable, worldwide, royalty-free, sublicensable license to use, modify, and incorporate the Feedback into any product or service without obligation or compensation. Please do not include third-party confidential information in Feedback.

Intellectual property in the Service

The Service — the engine, models, software, designs, trademarks, and documentation — is owned by TuringDNA or its licensors and is protected by intellectual-property laws. Subject to these Terms, we grant you a limited, revocable, non-exclusive, non-transferable license to access and use the Service for your internal research purposes. No other rights are granted.

"TuringDNA" and the TuringDNA logo are our marks. You may not use them without our prior written consent.

Open-source components

The Service incorporates open-source components, including the ESM-2 protein language models (MIT license, Meta AI Research) and other libraries. Those components are licensed under their respective open-source licenses, which prevail over these Terms with respect to those components only.

Copyright complaints (DMCA)

If you believe content on the Service infringes your copyright, send a notice that complies with 17 U.S.C. § 512(c) to info@turingdna.com with the subject line "DMCA Notice". Your notice must include: (a) identification of the copyrighted work; (b) identification of the allegedly infringing material and its URL; (c) your contact information; (d) a statement of good-faith belief that the use is not authorized; (e) a statement under penalty of perjury that the information is accurate and you are authorized to act; and (f) your physical or electronic signature. We may remove allegedly infringing material and terminate repeat infringers' accounts.

Marketplace — DNA synthesis orders

The Marketplace is not yet live. This section describes how it will work when it ships. You can use the engine today without ordering synthesis.

Role of TuringDNA

When the Marketplace launches, TuringDNA will operate it as an authorized reseller of synthesized DNA from participating third-party vendors — initially Twist Bioscience, Integrated DNA Technologies (IDT), and GenScript (each a "Vendor"). You contract with TuringDNA for the supply of DNA; we contract with the Vendor for its manufacture and shipment to you.

Vendor manufacture and flow-down

The DNA itself is manufactured by the Vendor you select. Vendor warranties, specifications, turnaround times, shipping policies, and biosecurity flow-down obligations govern the physical product. Where a Vendor's standard terms conflict with these Terms with respect to the manufactured DNA, the Vendor's terms control as to product specifications, manufacturing tolerances, screening outcomes, and shipping. Current Vendor terms will be linked from your order confirmation and incorporated by reference when you place an order. You agree to comply with any Vendor flow-down obligations applicable to your use.

Biosecurity screening

Each Vendor performs its own sequence screening under the IGSC Harmonized Screening Protocol or equivalent. You are responsible for ensuring your order complies with all applicable biosecurity laws (see Acceptable Use above and the Biosecurity Policy). We may decline, hold, or cancel orders at our discretion, including based on Vendor screening results or our own review, without liability. We may share order details with biosecurity authorities where reporting is required by law or by a Vendor agreement.

Orders, pricing, and payment

• Prices are shown at checkout in U.S. dollars unless stated otherwise and are inclusive of TuringDNA's margin and the Vendor cost. Prices may change at any time before you place an order; once we send an order confirmation, the price stated in that confirmation is binding except where the order is cancelled.
• An order is accepted only when we (or the Vendor) send you a confirmation. We may decline any order.
• Payment will be processed by our payment processor named at checkout. By placing an order you authorize the charge.
• You are responsible for applicable taxes, duties, customs fees, and import requirements.

Shipping, title, and risk of loss

• Shipping is performed by the Vendor or its designated courier. Estimated delivery times are not guaranteed.
• For business users: title and risk of loss pass on delivery to the carrier (FCA Incoterms 2020 at the Vendor's facility), unless a Vendor's terms specify otherwise (in which case the Vendor's terms control).
• For consumer users in jurisdictions whose mandatory law provides otherwise (e.g., EU Consumer Rights Directive, UK Consumer Rights Act, California Civil Code), risk of loss passes on delivery to you. Nothing in this section limits your non-waivable consumer rights.
• You are responsible for receiving and storing the DNA appropriately and for customs clearance in your country.

Returns, refunds, and cancellations

• Custom-synthesized DNA is made to your specification and is non-returnable except where the delivered product fails Vendor specification.
• If the delivered DNA fails Vendor specification, your remedy is governed by the Vendor's warranty (typically resynthesis or refund of the synthesis cost). We will use commercially reasonable efforts to pass through Vendor remedies to you.
• Orders may be cancelled before manufacture begins. Once manufacture has begun, cancellation is at the Vendor's discretion.
• EU/UK consumer withdrawal right. Custom-synthesized DNA is goods made to a consumer's specification and is excluded from the 14-day statutory right of withdrawal under EU Directive 2011/83/EU Article 16(c) and UK Consumer Contracts Regulations 2013 reg. 28(1)(b). For non-custom items (e.g., catalog kits, if any), the 14-day right applies.

Limited reseller warranty

Other than passing through Vendor warranties as described above, TuringDNA disclaims all warranties on the manufactured DNA itself, including merchantability, fitness for a particular purpose, and non-infringement, to the maximum extent permitted by law. This disclaimer does not limit your non-waivable consumer rights under applicable law.

Third-party services

The Service may integrate with optional third-party tools (for example, NCBI BLAST and AlphaFold lookups). These run only when you explicitly opt in for a given run. Your use of those tools is governed by their own terms. We are not responsible for third-party services.

Plans, fees and payment

This section applies to purchases made on or after 2026‑09‑11. You accept it when you buy; it changes nothing for free use of the engine.

Free plan. The engine is available free of charge within the usage limits shown in the app. Free features may be changed or removed without notice.

Paid plans. We may offer paid subscriptions, one-time purchases such as additional compute credits, and written agreements for organisations. What each option includes, and its price, is shown to you before you buy.

Our reseller. Our order process is conducted by our online reseller Paddle.com. Paddle.com is the Merchant of Record for all our orders: it processes your payment, issues your receipt and invoice, collects any applicable sales tax or VAT, and handles billing enquiries and refunds. When you buy, you also agree to Paddle’s Buyer Terms.

Renewal and cancellation. Subscriptions renew automatically at the end of each billing period until cancelled. You can cancel at any time; cancellation takes effect at the end of the current billing period, and you keep access until then. Refunds are governed by our Refund & Cancellation Policy and Paddle’s Refund Policy.

Price changes. We will give at least 30 days’ notice of a price increase or a material change to a paid feature. It applies from your first billing period after the notice ends.

Termination

You may stop using the Service at any time. To delete your account, sign in and use Delete my account on your dashboard: it erases Your Content at once, and, if you have an active paid plan, cancels it with Paddle as part of the same action. You can also email info@turingdna.com if you can no longer sign in. We may suspend or terminate your access immediately if you breach these Terms, if required by law, or to protect the Service, our Vendors, or other users.

Data export window. If we terminate your account for reasons other than breach of Acceptable Use or biosecurity law, we will keep it in a read-only state for 30 days so you can export Your Content, then delete it in line with the Privacy Policy retention schedule. When you delete your own account, no read-only window applies — deletion is immediate.

The sections on engine-output disclaimer, Your Content, Feedback, Intellectual Property, the Limited Reseller Warranty, Disclaimers, Research Use Only, Indemnification, Limitation of Liability, Governing Law and Venue, Changes, and Miscellaneous survive termination.

Disclaimers

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTY OF ANY KIND. TO THE FULLEST EXTENT PERMITTED BY LAW, TURINGDNA DISCLAIMS ALL WARRANTIES, EXPRESS, IMPLIED, OR STATUTORY, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, AND ANY WARRANTY ARISING FROM COURSE OF DEALING OR USAGE OF TRADE.

WITHOUT LIMITING THE FOREGOING, TURINGDNA DOES NOT WARRANT THAT (A) ENGINE OUTPUTS ARE ACCURATE, FUNCTIONAL, OR FIT FOR YOUR PURPOSE; (B) DESIGNED VARIANTS WILL EXPRESS, FOLD, OR EXHIBIT INTENDED PROPERTIES; (C) THE SERVICE WILL BE UNINTERRUPTED, SECURE, OR ERROR-FREE; OR (D) SEQUENCES YOU DESIGN ARE FREE FROM THIRD-PARTY PATENT OR OTHER RIGHTS.

Beta features. Features labeled "beta", "preview", "experimental", or similar are provided for evaluation and may be modified or withdrawn at any time. They carry no service-level commitment.

Research use only

THE SERVICE AND ANY DNA ORDERED THROUGH IT ARE FOR RESEARCH USE ONLY ("RUO"). THEY ARE NOT MEDICAL DEVICES, NOT FDA-CLEARED OR APPROVED, AND ARE NOT INTENDED FOR DIAGNOSTIC, THERAPEUTIC, PROPHYLACTIC, FOOD, FEED, OR COSMETIC USE, OR FOR USE IN OR ON THE HUMAN OR ANIMAL BODY. YOU ARE SOLELY RESPONSIBLE FOR REGULATORY COMPLIANCE FOR ANY DOWNSTREAM USE.

Indemnification

You will defend, indemnify, and hold harmless TuringDNA, its officers, directors, employees, and agents from and against any third-party claims, losses, liabilities, damages, and expenses (including reasonable attorneys' fees) arising from or related to: (a) Your Content; (b) your use of the Service or any DNA ordered through it; (c) your violation of these Terms or applicable law (including biosecurity, export, and safety law); (d) your downstream use of designed variants or synthesized DNA; and (e) any claim that Your Content infringes a third-party right.

Carve-outs. This indemnity does not apply to the extent a claim arises from (i) TuringDNA's gross negligence or willful misconduct, or (ii) TuringDNA's own infringement of a third party's intellectual property in the Service's underlying software (excluding Your Content). We will give you prompt notice of any claim, reasonable cooperation in the defense, and the right to control the defense and any settlement that does not impose obligations on you beyond payment.

Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, TURINGDNA WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, LOST REVENUE, LOST DATA, OR BUSINESS INTERRUPTION, ARISING OUT OF OR RELATED TO THE SERVICE, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

TURINGDNA'S TOTAL CUMULATIVE LIABILITY ARISING FROM OR RELATED TO THESE TERMS OR THE SERVICE WILL NOT EXCEED THE GREATER OF (A) THE AMOUNTS YOU PAID TO TURINGDNA IN THE TWELVE (12) MONTHS PRECEDING THE EVENT GIVING RISE TO LIABILITY, OR (B) ONE HUNDRED U.S. DOLLARS (USD $100).

These limits apply in the aggregate to all claims and theories of liability and are an essential basis of the bargain.

Non-waivable rights. Nothing in this section excludes or limits liability that cannot be excluded or limited under applicable law, including (where applicable) liability for death or personal injury caused by negligence, fraud, intent, or gross negligence (which under Georgian civil law cannot be excluded in advance), or for breach of mandatory consumer-protection law. Where local law caps or invalidates portions of this section (for example, the Law of Georgia on the Protection of Consumer Rights (2022), EU consumer law, the UK Consumer Rights Act, or certain U.S. state laws), our liability is limited to the maximum extent permitted by that law.

Governing law and venue

These Terms are governed by the laws of Georgia (the country), where TuringDNA is registered as an Individual Entrepreneur, without regard to conflict-of-laws principles that would apply the law of another jurisdiction. The United Nations Convention on Contracts for the International Sale of Goods (Vienna, 1980) does not apply to any order placed through the Service, even where Georgia and your country are both parties to it.

Courts. Except as set out in the Consumer carve-out below, any dispute arising out of or related to these Terms or the Service will be brought exclusively in the competent courts of Tbilisi, Georgia (Tbilisi City Court at first instance, under Georgia’s Civil Procedure Code), and each party consents to their personal jurisdiction and venue.

Optional arbitration for business users. Where both parties are acting in the course of a trade or profession, we may agree in a separate signed writing to submit a specific dispute instead to arbitration at the Georgian International Arbitration Centre (GIAC) in Tbilisi, under its Arbitration Rules, in English, by a sole arbitrator. Georgia has been a party to the New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards (1958) since 1994, so a GIAC award is enforceable in the courts of every other contracting state. This clause does not apply to consumers.

Consumer carve-out. If you use the Service as a consumer (a natural person acting outside their trade, business, craft, or profession), nothing in this section can strip you of protection that is mandatory under the law of your country of habitual residence. In particular:

• Consumers in Georgia keep the non-waivable rights of the Law of Georgia on the Protection of Consumer Rights (2022) — including the 14-day distance-contract withdrawal right, the trader’s burden of proof for defects reported in the first six months, pre-contract information duties, and the automatic invalidity of unfair terms — and may bring proceedings in the court of their own place of residence.
• Consumers in the EU, the EEA, the UK, or Switzerland keep the mandatory consumer-protection rules of their country of habitual residence (Article 6(2) of EU Regulation 593/2008, Rome I), and may bring proceedings against us in the courts of that country and may only be sued there (Article 18 of EU Regulation 1215/2012, Brussels I recast, and equivalent UK and Swiss rules).
• Consumers elsewhere keep any equivalent non-waivable rights their home country provides.

Changes to these Terms

We may update these Terms from time to time. If we make material changes, we will notify you (e.g., by email or in-app notice) at least 30 days before they take effect. Continued use after the effective date constitutes acceptance. If you do not agree to material changes, your remedy is to stop using the Service before the effective date and to request account deletion.

Miscellaneous

• Entire agreement. These Terms and the Privacy Policy are the entire agreement between you and TuringDNA regarding the Service and supersede any prior agreements.
• Severability. If any provision is held unenforceable, the rest remain in effect; the unenforceable provision will be enforced to the maximum extent permitted by law.
• No waiver. Failure to enforce any provision is not a waiver.
• Assignment. You may not assign these Terms without our consent. We may assign them in connection with a merger, acquisition, financing, or sale of assets on notice to you.
• Force majeure. Neither party is liable for delays caused by events beyond reasonable control (including acts of God, war, civil unrest, internet/cloud outages, pandemics, government action, and vendor failure).
• Independent contractors. No agency, partnership, joint venture, or employment is created by these Terms.
• Notices. Notices to TuringDNA: info@turingdna.com. Notices to you: the email associated with your account. You consent to receive electronic notices.
• Headings. Section headings are for convenience and do not affect interpretation.
• English controls. These Terms are written in English; any translation is for convenience only and the English version controls in case of conflict.
