These Terms of Service (the "Terms") govern your use of the BlueLetter mobile application and any related services ("BlueLetter," "the app," "the service"). BlueLetter is operated by Marco Santini, an individual operator established in the Netherlands ("we," "us," "the operator").
By installing, accessing, or using BlueLetter you confirm that you have read, understood, and agreed to these Terms. If you do not agree, do not install or use the app.
BlueLetter is a mobile translation aid. You take a photo of a Dutch government letter using your device camera or upload an existing image; BlueLetter sends the image to a large-language-model AI provider, and returns:
BlueLetter is a convenience tool. It is not an official translation service, a notarised translation, a sworn translator, a tax advisor, an immigration advisor, a lawyer, an accountant, a financial advisor, a debt-collection agent, or a government authority.
You may use BlueLetter only if you are at least 17 years old, have the legal capacity to enter into a binding contract under the laws of your country of residence, and are not prohibited from using digital services under any applicable export, sanctions, or other law.
If you are using BlueLetter on behalf of another person (for example helping a parent or partner read their post), you confirm that you have their permission to scan and process letters addressed to them, and that they have read and accepted these Terms.
Some features of BlueLetter may require an account. You are responsible for the accuracy of the information you provide and for keeping your credentials confidential. You are responsible for all activity carried out under your account. Notify us at support@tryblueletter.com if you suspect unauthorised use.
BlueLetter offers three tiers:
Standard and Pro are sold as auto-renewing subscriptions with monthly or annual billing cycles. Subscriptions are sold and billed by Apple through the Apple App Store. Apple is the merchant of record. Apple is responsible for handling payment, refunds, taxes, and subscription management. Apple's terms apply to the payment relationship: https://www.apple.com/legal/internet-services/itunes/.
Subscriptions renew automatically at the end of each billing period unless you cancel at least 24 hours before the renewal date via your Apple ID subscription settings. Prices and features may change with notice as described in section 16.
Tax (VAT) is included where it applies. Apple handles VAT collection and remittance.
If you are a consumer resident in the European Union, the United Kingdom, or another jurisdiction that grants you a statutory right of withdrawal for digital services, you have the right to withdraw from a subscription contract within fourteen (14) days of purchase, without giving any reason.
However, by purchasing a subscription and starting to use BlueLetter's paid features within the withdrawal period, you expressly request that we begin providing the service immediately and acknowledge that you lose your right of withdrawal once the service has been fully performed, as permitted under Article 16 of EU Directive 2011/83/EU. Each individual letter scan and AI translation is considered a fully performed service for this purpose.
If you wish to withdraw from a subscription within the 14-day window and have not used any paid features, you must request a refund through Apple's standard refund flow: https://reportaproblem.apple.com. We are unable to issue refunds directly because we do not process your payment.
BlueLetter uses third-party large-language-model AI to read and interpret the images you upload. The model used at the time of writing is Anthropic Claude, accessed through the Anthropic API. The model used may change over time without notice to you.
Specifically and without limitation, BlueLetter does not:
To deliver the service, BlueLetter shares letter-image data with the following providers:
For full details of how your data is processed, see our Privacy Policy. We do not sell your personal data and do not use letter content to train AI models.
For matters concerning Dutch government correspondence — and in particular letters from Belastingdienst, IND, DUO, CJIB, UWV, Gemeente, KvK, courts, debt-collection agencies, or insurers — you should consult a qualified professional (such as a registered tax advisor, immigration lawyer, civil-law notary, or social-services advisor) before taking any action that could affect your finances, residence status, legal standing, or rights.
By using BlueLetter you accept that you have an independent obligation to:
If you act on a BlueLetter translation or summary without independently verifying the original Dutch text, you do so at your sole risk.
You agree not to:
We may suspend or terminate your access if you breach this section.
BlueLetter, its design, branding, code, and content are owned by Marco Santini and protected by applicable intellectual-property law. We grant you a limited, revocable, non-exclusive, non-transferable, non-sublicensable licence to install and use BlueLetter on a device you own or control, for personal and non-commercial purposes only.
The letters you scan remain yours. We do not claim any ownership of the content of your letters or of the translations and summaries we produce for you. You grant us a limited licence to process your letter content as necessary to provide the service (including sending it to the AI provider).
We may use aggregated, anonymised technical data — such as scan counts and error rates — to improve the service.
Our handling of your personal data is described in our Privacy Policy, which is incorporated into these Terms by reference. We process personal data in accordance with the EU General Data Protection Regulation (GDPR) and the Dutch Uitvoeringswet AVG. By using BlueLetter you confirm that you have read and understood our privacy practices.
We aim to keep BlueLetter available continuously but we do not guarantee uninterrupted service. The app depends on third-party services — including but not limited to the Anthropic API, Vercel, Apple App Store services, Apple Push Notification Service, and your device's calendar and notification subsystems — whose availability is outside our direct control.
We may also temporarily suspend the service for maintenance, security, capacity, or upgrade reasons. We will use reasonable efforts to schedule planned downtime outside peak hours but cannot always do so.
We are not liable for any failure or delay in performance caused by events beyond our reasonable control, including acts of God, natural disasters, war, terrorism, civil unrest, cyber-attacks, internet or telecommunications failures, third-party service outages, governmental action, public-health emergencies, or labour disruptions.
To the maximum extent permitted by applicable law:
Nothing in this section excludes warranties that cannot be excluded under applicable consumer-protection law.
You may stop using BlueLetter and cancel any subscription at any time through your Apple ID settings.
We may suspend or terminate your access if (a) you breach these Terms, (b) we are required to do so by law or court order, (c) a third-party service we depend on terminates its relationship with us, (d) the operator ceases to operate BlueLetter as a business. We will give you reasonable notice where practical.
Sections 6, 8, 9, 11, 12, 14, 17, 18, 19, and 20 survive termination of these Terms.
We may update these Terms from time to time. When we make a material change, we will:
Non-material changes (typographical corrections, clarifications, new feature descriptions that do not affect your rights) may take effect immediately. Continued use of BlueLetter after the effective date of a change constitutes acceptance of the updated Terms.
To the maximum extent permitted by applicable law:
We are not liable for:
Our total cumulative liability to you for any direct damages arising out of or in connection with BlueLetter is limited to the greater of: (a) the total amount you paid to us through your subscription in the twelve (12) months preceding the event giving rise to the claim, or (b) one hundred euro (€100).
Nothing in these Terms limits or excludes any liability that cannot lawfully be limited or excluded, including without limitation liability for: (a) personal injury or death caused by our negligence, (b) fraud or fraudulent misrepresentation, (c) intentional misconduct or gross negligence, (d) any other liability that cannot be excluded under mandatory consumer-protection law in your country of residence.
If you are a consumer resident in the European Union, your statutory rights under Directive 1999/44/EC, Directive 2011/83/EU, the Dutch Civil Code (Burgerlijk Wetboek), and the GDPR are not affected by these Terms.
You agree to indemnify, defend, and hold harmless Marco Santini, BlueLetter, and any of our affiliates, contractors, employees, or service providers, from and against any third-party claims, demands, losses, liabilities, damages, costs, and expenses (including reasonable legal fees) arising out of or related to:
This indemnification obligation survives termination of these Terms. It does not apply to the extent the claim arises out of our own intentional misconduct or gross negligence.
These Terms are governed by the law of the Netherlands, excluding its conflict-of-law rules and excluding the United Nations Convention on Contracts for the International Sale of Goods.
Any dispute arising out of or in connection with these Terms or your use of BlueLetter will be subject to the exclusive jurisdiction of the competent courts of Amsterdam, the Netherlands.
If you are a consumer resident in the European Union, this clause does not deprive you of the protection afforded to you by mandatory provisions of the law of your country of residence, and you may bring proceedings before the courts of your country of residence to the extent permitted by law.
The European Commission provides an Online Dispute Resolution platform for consumer disputes: https://ec.europa.eu/consumers/odr/. We are not required to and do not commit to participating in alternative dispute resolution.
If any provision of these Terms is held to be invalid, illegal, or unenforceable by a court or authority of competent jurisdiction, that provision shall be modified to the minimum extent necessary to make it enforceable, or, if it cannot be so modified, struck from these Terms. The remaining provisions shall continue in full force and effect.
Our failure to enforce any right or provision of these Terms shall not be deemed a waiver of that right or provision. A waiver of any breach shall not be deemed a waiver of any subsequent breach.
These Terms, together with our Privacy Policy and any feature-specific notices presented inside the app, constitute the entire agreement between you and us regarding BlueLetter and supersede any prior agreement or understanding.
You may not assign or transfer your rights or obligations under these Terms without our prior written consent. We may assign or transfer our rights and obligations under these Terms in connection with a corporate restructuring, sale of business, or similar transaction, provided that any successor undertakes to honour these Terms.
These Terms are drafted in English. Translations may be provided for convenience; in case of conflict, the English version prevails.
