Terms and conditions

sdev.in (the "site", "we", "us") is an independent site published from India. By using the site, its courses, its tools or the sdev browser extensions you agree to these terms. If you do not agree, please do not use them. The courses, the tools and the free features of the extensions need no account. These terms, the privacy policy and the refund and cancellation policy are the whole agreement between us.

The tools run in your browser and process your own files and text. You are responsible for what you put into them and for checking the result before you rely on it. A merged PDF, a compressed image, a hash or a converted file should be verified by you before it is sent, published or signed.

You keep all rights to the content you process. Because the tools do not upload your files, the site never takes a copy of them. See the privacy policy for the few cases where a tool fetches a web address on your behalf.

An account is only needed for Pro and for keeping work online, such as saved designs, name lists and certificate checks. You create it by signing in with Google, and you must be 18 or older. One account is for one person; do not share it. Keep your Google account secure, and tell us straight away at hello@sdev.in if you think someone else has used your sdev.in account.

You can delete your account at any time from the Account page. We may suspend or close an account that breaks these terms, is used for fraud or abuse, or puts the service or other users at risk. Where it is fair to do so, we will tell you first and give you a chance to fix the problem.

Pro adds paid features to the sdev extensions, such as your own watermark, backgrounds, your name in file names and extra PDF options. The Pro page lists what is included and the current prices. Everything else stays free. You may try Pro features in the extension before you buy; without Pro they are left out of what you save.

• Billing. Pro is a monthly, yearly or 5-year subscription, charged through Razorpay in Indian rupees, or in US dollars where the Pro page shows dollar prices. Plans for schools, colleges and offices work the same way. Prices include applicable taxes, and you get an invoice for each payment. The subscription renews automatically at the end of each period until you cancel.
• Cancelling. You can cancel at any time from the Account page. Pro then stays active until the end of the period you have paid for and does not renew. Refunds are covered by the refund and cancellation policy.
• Failed payments. If a renewal payment fails, Razorpay retries it. If it still fails, Pro pauses until the payment goes through.
• Price changes. A new price never applies to a period you have already paid for. Subscribers are emailed at least 30 days before a new price applies to them, and can cancel before then.
• Devices. One Pro subscription can be used in up to 3 browsers at a time. You can remove a browser from the Account page to use Pro somewhere else.
• Licence. Pro gives you a personal, non-transferable right to use the Pro features while your subscription is active. Pictures you make with Pro stay yours after it ends.

If a Pro feature is withdrawn during a period you have paid for, you can ask for a refund of the unused part of that period.

You can support sdev with a voluntary contribution from the Support page. Thank you: every contribution helps us build and improve the tools.

• A gift, not a purchase. A contribution does not buy Pro, a feature, priority help or any other goods or services, and your use of the site is the same whether or not you contribute.
• Final once made. Because contributions are gifts, they are not refundable. Please check the amount, and whether you want it to repeat monthly, before you pay.
• Monthly contributions can be stopped at any time: cancel the AutoPay mandate in your UPI app, or write to hello@sdev.in and we cancel it within 2 working days (Buy Me a Coffee monthly support is cancelled on its own page). Nothing more is charged after that, and contributions already made stay final.
• Payment partners. Payments are taken on pages run by Razorpay (in India) or Buy Me a Coffee (from other countries), under their own terms. If a payment was made without your permission, contact your bank or card issuer, and let us know at hello@sdev.in.

Nothing here limits any right you have under the law that applies to you.

You agree not to:

• use the site or its URL fetching features to attack, overload or scrape other sites;
• process content you do not have the right to use, or content that is unlawful;
• try to break, probe or interfere with the site, the extensions, the account server, its hosting or its analytics, or get around the checks that decide who has Pro;
• create accounts automatically or in bulk, or resell or share Pro access;
• send spam, advertising or automated messages through the contact form, or messages that are abusive or unlawful;
• republish the site's pages, text or videos as your own, or wrap the tools in another site without permission.

The certificate, ID card, event badge, visiting card and stamp makers exist to save time for schools, colleges, offices, shops, clubs and event teams that make their own documents. Use them only for documents you have the right to issue: for your own organisation, for an organisation that has allowed you to, or for clearly personal use such as practice, samples or invitations.

You agree not to use them to:

• make a fake, copied or altered certificate, mark sheet, ID card, licence, pass, stamp or seal, or one that claims to come from someone who did not issue it;
• use the name, logo, seal or signature of a government office, school, college, company or person without their permission;
• use the State Emblem of India or any other official emblem or mark, except where the law allows you to;
• deceive or cheat anyone, or support any other unlawful purpose.

Making or using a forged document or a fake seal is a serious offence under Indian law and the laws of other countries. You alone are responsible for what you make, download, print and share with these tools, and for making sure it is lawful. Anyone who misuses them faces the legal consequences personally. sdev.in only provides the tools: we do not check, approve or vouch for any document made with them, and we are not responsible for how they are used.

An online check page shows that a record exists on the issuer's sdev.in account. It does not mean that sdev.in has checked the issuer or the document. If we learn that the tools or a check record are being misused, we may withdraw or delete the records, suspend the account, and share information with the police or a court when the law requires it. To report misuse, use the contact form.

The courses are free YouTube videos in Tamil and English. They are for learning and are provided as they are. Code shown in a video may be used in your own projects without attribution. Watching a video on this site is also subject to YouTube's terms of service.

The rasi palan, peyarchi palan, puthandu palan, nalla neram, muhurtham dates and festival dates on this site are worked out from traditional rules and the position of the sky. They are general guidance and are shared for cultural interest. They are not a promise of what will happen, and they are not professional advice of any kind.

Every life is unique. Before you fix an important date, such as a wedding, a house warming or a new venture, please check it with your temple priest or family astrologer, and talk with the right professional about health, money or legal matters.

Times change with the city you pick and with the almanac system (Drik or Vakya), so the same day can show slightly different times in different calendars. sdev.in is not an astrologer, priest, medical, financial or legal adviser and is not responsible for decisions made from these results.

The information on the site is general and is shared in good faith. We work to keep it right, but we do not promise that it is accurate, complete or up to date, and it may contain errors or omissions.

Results from the calculators, the gold, silver and egg rates, the panchang and calendar, and the health, pregnancy, baby, eye and hearing tools are estimates. Rates can differ from what a shop charges, and a health tool is not a medical test. Before you rely on an important result, check it with an official source or a qualified professional, such as your bank, tax adviser, doctor or the department concerned. If you spot a mistake, please tell us at hello@sdev.in so we can fix it.

Ratings, reviews and comments from visitors are their own opinions, not ours, and your results may be different. We may shorten a review for length, fix obvious typos, or remove one that is spam, abusive or unlawful, without changing what it means.

Ads may appear on the site, and they help pay for running it. Ads are chosen by the ad network, not by us. Showing an ad does not mean that we endorse, recommend or check the product, service or company in it.

The design, text, logos and videos of the site belong to sdev.in unless stated otherwise. Open source libraries used by the tools stay under their own licences.

Names, trademarks and logos of third-party products, companies, banks and government services mentioned on the site belong to their owners. They are used only to describe what a tool works with or helps you do. Naming them does not mean that they endorse, sponsor or are connected with sdev.in.

The site links to YouTube, Google Maps, app stores, public CORS proxies and other services that we do not control, and payments are processed by Razorpay. We are not responsible for their content, availability or how they handle your data. Follow their terms when you use them.

The site, courses, tools and extensions are provided "as is" and "as available", without any warranty, express or implied, including fitness for a particular purpose, accuracy or that they will be free of errors or interruptions. Free tools and features may change, break or be removed at any time. This does not limit any rights you have by law as a paying customer.

To the fullest extent allowed by law, sdev.in is not liable for any loss or damage arising from your use of the site, including lost data, lost profits or damage from relying on a tool's output or a course's content. Where liability cannot be excluded, it is limited to the amount you paid for Pro in the 12 months before the claim, or nothing if you have not paid.

These terms are governed by the laws of India. Any dispute will be handled by the courts of India. If any part of these terms is found unenforceable, the rest still applies.

These terms may be updated from time to time. The date at the top shows the current version, and continuing to use the site after a change means you accept the new terms. Account holders are emailed about changes that affect them at least 30 days before they take effect, and can delete their account or cancel Pro before then.

Questions about these terms, mistakes on a page or problems with a tool go to hello@sdev.in or through the contact page. We reply as soon as we can.
