Privacy
Updated November 1, 2026.
Tendio stores the account information, maintenance records, photos, and files you choose to save. These are used to provide your plan, sync your records, and support your account.
Service providers
Supabase provides account authentication, database storage, and private file storage. Vercel hosts the website. When you enable email reminders, the configured email provider (Resend) processes your email address and reminder content. If you purchase a subscription, Stripe or Apple processes the payment; Tendio stores subscription identifiers and status rather than card numbers. Optional AI features use OpenAI through Tendio. When you request photo identification, receipt reading, assistant help, or additional maintenance suggestions, the request may include your message, relevant saved task and asset details, service titles and dates where used, and any image or manual excerpt you add. Review the feature’s disclosure before sending information and check suggested results before saving them.
Household sharing
You can invite a verified Tendio account to view selected assets and their task status. You can also choose to share service dates and task titles. Addresses, serial numbers, private files, service notes, and costs are excluded from household views. Invitations are tied to the account email you specify and expire after seven days. You can revoke access, and members can leave a share. Service briefs include only the asset, tasks, history, and optional fields you select; review the preview before sharing a printed or exported copy.
Your controls
You can edit records, archive items, download your data and attachments, and control reminders. Archived items remain stored until deleted. You can delete your account after signing in and confirming your password. This removes your live account records and files. Backups may retain copies under their retention policies, and exported or offline copies on other devices are not erased. A minimal deletion receipt is retained to confirm completion and prevent replay. AI usage and spending records are retained to enforce the service’s spending limits. For help accessing your information, contact support@tendioapp.com.
Storage and access
Account sessions use browser storage. Private files are opened through temporary links. Do not share those links with people who should not see the files. Tendio does not sell your maintenance records or use advertising trackers.
