By accessing or using DevTools by Hakeemify ("DevTools", "we", "us", "our") at devtools.hakeemify.com, you agree to be bound by these Terms of Service. If you do not agree to these terms, please do not use the service.
DevTools provides a suite of free, browser-based developer utilities including but not limited to RegexLab, CronBuilder, JSONCraft, HashLab, URLInspector, DiffViewer, ColorSystemPro, InvoiceZen, CSVStudio, and APITester. Core functionality of all tools is provided free of charge and does not require an account. Optional Pro subscriptions unlock additional features such as saving and syncing data across devices.
Creating an account is optional and only required to access Pro features. You are responsible for maintaining the confidentiality of your account credentials and for all activity under your account. You must provide accurate information when registering.
Pro plans are billed monthly, yearly, or as a one-time Lifetime payment, in either BDT (via AamarPay, for users in Bangladesh) or USD (via Lemon Squeezy, for international users). Prices are displayed clearly before purchase. Monthly and yearly subscriptions do not auto-renew by default; you may renew manually before expiry. Lifetime purchases are one-time payments with no recurring charges. All payments are processed by our third-party payment processors; we do not store your card details.
Refund requests are considered on a case-by-case basis within 14 days of purchase. Contact us at the email listed on hakeemify.com/contact with your order details to request a refund.
You agree not to: use the service for any unlawful purpose; attempt to gain unauthorized access to our systems or other users' data; use automated systems to scrape or overload the service; reverse-engineer or resell the service; or upload content that infringes on the rights of others.
Most tools (RegexLab, CronBuilder, JSONCraft, HashLab, URLInspector, DiffViewer, ColorSystemPro, CSVStudio, APITester) process all input entirely in your browser — nothing is sent to our servers unless you explicitly use a Pro "Save" feature. InvoiceZen generates PDFs locally using your browser's print engine. See our Privacy Policy for full details.
The DevTools name, logo, and platform code are the property of Hakeemify. You retain all rights to any content you create using the tools (regex patterns, JSON snippets, invoices, etc.).
We aim for high uptime but do not guarantee uninterrupted access. We may modify, suspend, or discontinue any part of the service at any time, with reasonable notice where practical for paid features.
DevTools is provided "as is" without warranties of any kind. We are not liable for any indirect, incidental, or consequential damages arising from your use of the service, including but not limited to data loss, business interruption, or errors in generated output (regex patterns, cron expressions, invoices, code snippets, etc.). Always verify critical output before using it in production systems.
We may update these Terms from time to time. Continued use of the service after changes constitutes acceptance of the revised terms. Material changes will be reflected with an updated "Last updated" date below.
Questions about these Terms can be sent via hakeemify.com/contact.
