Using Calniva
These terms govern Calniva and its related services, operated by TSINGINC CO., LIMITED. By using Calniva, you agree to these terms. Contact tsinginc@gmail.com for questions. If you do not agree, do not use the service.
Calniva is for adults aged 18 and over. You receive a personal, limited, non-exclusive right to use the app in accordance with these terms and applicable Apple terms. The Apple Standard Licensed Application End User License Agreement applies to the app license where applicable.
Nutrition estimates and your decisions
Calniva supports general wellness, food recording and planning. It does not provide medical diagnosis, treatment or guaranteed health or weight results. Nutrition, calories, exercise energy and suggested targets are estimates or values entered by you. AI can make mistakes, omit ingredients and misjudge portions.
Review each result, food label, ingredient, portion and recipe before using it. A dietary preference or restriction does not guarantee that a recipe is allergy-safe. Consult an appropriate professional for medical conditions, pregnancy, eating disorders or other needs requiring individual care. Do not delay care because of app content.
Free features and Premium
Basic manual tracking and viewing saved records remain available without Premium. The free AI experience consists of one successful food analysis shared across camera, photo-library and text entries, rather than one per entry method. It is not a timed Apple subscription trial and does not start an automatic subscription. Unsuccessful analysis does not deliberately consume the experience.
One Premium membership unlocks advanced features, including AI analysis and corrections, personalized meal generation, recipe recreation, meal adjustments and advanced reports. Annual and monthly subscriptions provide the same Premium features. Reasonable technical, usage and abuse-prevention limits may apply to AI; Premium is not a promise of unlimited computational usage.
Purchases, renewal and cancellation
Apple handles purchases. Review the actual localized price, billing duration and renewal terms shown before confirming. Annual plans renew yearly; monthly plans renew monthly. Payment is charged to your Apple Account and subscriptions renew automatically unless canceled before renewal under Apple’s displayed terms.
Manage or cancel through Apple subscriptions. You can restore eligible purchases from within Calniva using the Apple Account that purchased them. Removing the app or deleting local records does not cancel your subscription. Restoring Premium does not restore a lost diary.
Billing and refund requests are handled through Apple, including Report a Problem, subject to applicable law. We cannot change Apple’s prices, billing records or refund decisions from inside the app. Features already saved locally remain your records; generating new Premium content requires active access.
Your content and local data
You retain rights in the photos, text and records you provide. You give us permission to process the content needed to carry out the actions you request, including sharing with the disclosed AI provider only after the app obtains permission. See the privacy policy.
Only submit content you are entitled to use. Do not submit unlawful content, unrelated personal information, or attempt to disrupt services, steal credentials, circumvent usage controls or resell shared access. Calniva’s design, software, branding and licensed assets are protected by their respective owners’ rights.
Your diary is stored locally. Keep your own exports before deleting the app, replacing a device or performing a reset. We cannot recover records that were never backed up or shared with us.
Availability and responsibility
AI requires internet access and depends on our hosting, Zhipu AI and device capabilities. Barcode data, Apple services and other integrations have their own availability and terms. We work to keep Calniva useful, but do not guarantee uninterrupted access, error-free results or a specific outcome.
To the extent permitted by applicable law, we are not responsible for indirect losses arising from inaccurate estimates, third-party interruptions, or local data you did not preserve. Nothing in these terms excludes responsibility that cannot lawfully be excluded or limits mandatory consumer rights, remedies or privacy rights. We may restrict misuse and will handle legitimate support concerns through the contact channel above.
Changes and contacting us
We may improve features and update these terms. The effective date identifies the current version. We will give appropriate notice of material changes, and Apple manages applicable subscription-change notices. If a concern cannot be resolved through support, any mandatory rights to contact regulators, seek consumer remedies or bring a claim in a competent court remain unaffected.
For questions, include “Calniva” and a short description when contacting tsinginc@gmail.com. Please do not send passwords or payment card details.
