Terms of Use
Crest Invoice is a personal software project operated by the Crest Invoice Team: Alina Riaby and Pavel Riaby.
These terms apply whenever you use Crest. When you choose a feature, you are asking Crest to run it under these terms. The Privacy Policy explains how Crest handles personal data. Email support@crest-invoice.com with any question.
Service and eligibility
Crest is a free, early-stage invoicing service with downloads and optional hosted invoices, sending, returning access and tracking. Crest is not a payment, legal, tax or accounting service.
You must be 18 or older, legally capable and authorised to issue invoices or act for the sender, including entering client data.
Features may change, pause or end. Where practicable, Crest gives reasonable notice and a workable way to save affected invoices first.
Your responsibilities
You are responsible for the accuracy and lawfulness of the identities, items, tax, currency, totals, dates, payment instructions, client data and delivery. Rules differ by country. Guides provide general information, not advice. Check the final invoice before sending it and keep the records the law requires.
You must have a lawful basis or authority for client data and sending invoices, and follow privacy and marketing rules.
Payments and third parties
Crest shows the payment instructions and links the invoice creator supplies, and can record a payment the client reports. Crest is not a payment processor and never receives, holds, routes, settles or guarantees funds. A payment report is not proof of settlement: verify receipt independently.
Payment availability, fees, exchange rates, fraud controls, refunds and disputes belong to the parties and payment providers. Third parties have their own terms and privacy practices. Crest answers for its own software and processing only.
Founding Lifetime costs $129 once, tax included, and grants every current and future Crest Pro feature for as long as Crest runs. You can request a full refund within 60 days of purchase by emailing support@crest-invoice.com; a refund revokes the entitlement. Stripe, Inc. processes Founding Lifetime payments and refunds as Crest's payment processor.
Acceptable use
You must follow these rules when using Crest.
- Do not create or send unlawful, deceptive, fraudulent, infringing or abusive invoices.
- Do not spread malware, phishing, spam or harassment.
- Do not impersonate others or use data without authority.
- Do not probe, bypass or disrupt security, access controls or rate limits.
- Do not run automated scraping or traffic that harms Crest or other users.
- Do not break applicable law or provider rules.
Crest may investigate and proportionately restrict abuse, preserving access to lawful data where feasible and lawful.
Your content, termination and availability
You retain your content rights. You license Alina Riaby and Pavel Riaby only to render, host, send and operate requested features. Crest retains software, site, documentation and brand rights, subject to stated licences.
You can stop using Crest at any time and delete hosted data in the product or by emailing support@crest-invoice.com. Crest may suspend or end access for material breach, abuse, security needs or legal requirements. Data is deleted or isolated under the Privacy Policy, including its rules for retained backups and necessary legal evidence.
There is no uptime promise. Maintenance, failures, provider interruptions or changes may interrupt Crest. Keep important invoices and records elsewhere.
Liability and disputes
To the extent the law allows, Crest provides the service and its guides as they are. Crest does not promise that every feature is uninterrupted or error-free, or that it suits a particular legal, tax or payment outcome. Checking invoices and payment receipt remains your responsibility.
Nothing in these terms limits responsibility for fraud, wilful misconduct, gross negligence, death or personal injury Crest causes, mandatory consumer rights, data-protection responsibility, or anything else the law does not allow to be excluded. Mandatory rights always prevail. These terms set no artificial money cap on liability.
Serbian law applies unless mandatory law overrides it. Before you start court proceedings, email support@crest-invoice.com so the issue can be resolved in good faith. Mandatory consumer, data-protection, jurisdiction, complaint and court rights remain. No exclusive court or arbitration venue applies.
Changes and contact
Email support@crest-invoice.com. Material changes receive appropriate notice; prior versions remain available. If the law requires you to agree separately to a new purpose or obligation, continuing to use Crest does not count as that agreement. Future paid subscriptions or payment services require separate terms before launch.
