Terms

Luma is for education and personal record-keeping only. It is not medical advice, does not diagnose or treat conditions, and does not replace professional healthcare. Its optional period estimates use confirmed records for planning only; they must not be used for fertility or contraception. For any health question, symptom or concern, seek advice from a qualified healthcare professional and never delay medical attention because of Luma. You control what you record and share; review any summary before sending it to another person. Responsible use, accuracy and liability: Use this app only for its stated purpose and follow its instructions and limitations. Check important inputs, estimates and third-party information independently before acting; they may contain errors or become outdated. You use the app and make decisions based on its output at your own risk, subject to the rights and responsibilities below. Thiago Gouvea, an independent developer, is not responsible for loss caused by misuse, incorrect information you supply, or use contrary to the app’s stated instructions, except where we are legally responsible. We do not guarantee the accuracy, completeness or availability of third-party data. This does not exclude responsibility for our own failure to meet applicable legal obligations. Nothing in these terms excludes or limits your statutory consumer rights, liability for fraud or fraudulent misrepresentation, death or personal injury caused by negligence, or any liability that cannot lawfully be excluded or limited. Pricing may change at any time for future purchases. Check the applicable price shown in the store before buying; a later price change does not change a purchase already completed.
