Frequently Asked Questions

Memento Database is a powerful and flexible database application that helps you organize any type of information. We created Memento with a simple vision: to empower anyone, regardless of technical background, to build their own custom applications tailored to their unique needs. Whether you're running a small business or managing personal projects, Memento lets you design and create your own app-like solution without writing a single line of code. Instead of adapting your workflow to fit generic software, you can build exactly what you need - from inventory tracking and CRM systems to personal collections and project management - all within one intuitive platform available across Android, iOS, and Desktop.

No. Memento Database is designed for users of all skill levels. You can create databases using intuitive wizards and templates without any coding knowledge. Advanced users can optionally use JavaScript for automation and complex calculations.

Memento Database is available on Android, iOS (iPhone and iPad), Windows, macOS, and Linux. All your data syncs seamlessly across all platforms through Memento Cloud, so you can access and update your databases from any device.

Mobile versions (Android and iOS) work fully offline. You can create and use local libraries without an internet connection, and cloud libraries can be accessed and modified offline - changes will sync automatically when you reconnect. Desktop versions (Windows, macOS, Linux) require an internet connection to access cloud libraries.

Yes, Memento takes security seriously. Memento Cloud is powered by Google Cloud, providing enterprise-grade infrastructure and security. All data transmitted to and from Memento Cloud is encrypted using industry-standard SSL/TLS protocols. Data at rest is also encrypted on Google Cloud servers. Additionally, you can create encrypted libraries on Android for extra protection, securing sensitive data with a password using AES-256 encryption.

Yes! Memento is free to use forever. The Free plan includes 100 MB of cloud storage with 3 cloud libraries, unlimited local libraries on mobile devices, and 200 AI credits per month. You can create unlimited entries - the only limit is your storage space. This makes it perfect for personal use and trying out the app. When you need more storage, unlimited cloud libraries, or advanced features, you can upgrade to Lite, Pro, or Team plans.

Pro plan unlocks all PRO features on all platforms, including unlimited automation rules, scripts, widgets, charts, advanced search, enhanced AI with 2000 monthly credits, multiple objects per field, Google Sheets sync, and more. Free plan has limitations on the number of rules, scripts, widgets (1-2 per library) and doesn't include advanced features.

Yes, you can cancel your subscription at any time. Your paid features will remain active until the end of your current billing period. After cancellation, your account will revert to the Free plan, and your data will remain safe - you'll just have the limitations of the Free plan.

AI credits are used when you interact with Memento's AI Assistant powered by ChatGPT-4 and Claude. Each query consumes a certain number of credits depending on complexity. Free and Lite plans include 200 credits/month, Pro includes 2000, and Team includes 3000 per user. Unused credits do not roll over to the next month.

A Library is Memento's term for a database table. It contains Fields (columns that define data types) and Entries (rows with actual data). Each Library can have multiple pages, aggregations, and relationships with other Libraries.

Memento supports over 30 field types including text, markdown, numbers (integer and decimal), currency, dates, times, checkboxes, dropdown lists, choice fields, tags, ratings, images, files, audio, signatures, barcodes, phone numbers, email addresses, hyperlinks, contacts, locations with GPS coordinates, calculations, and JavaScript fields.

Yes. Memento supports relational database functionality through "Link to Entry" fields, allowing you to create one-to-one, one-to-many, and many-to-many relationships between Libraries.

You can organize fields using Pages (separate screens) and Subheaders (visual dividers within a page). This makes complex databases with many fields easier to navigate and use.

Calculated fields automatically compute values based on other fields using mathematical, logical, date/time, or string functions. For example, you can calculate totals, discounts, age from birthdate, or conditional values.

You can add entries manually one at a time, import data from CSV files, use web forms to collect data from others, generate entries with AI assistance, or auto-populate entries from web services (for items like books, movies, and products with barcodes).

Yes. Web Forms allow anyone to submit data through a web browser without installing Memento Database. You can create custom forms with specific fields and control access through public links, passwords, or user restrictions.

Yes. Memento supports CSV import, which works with Excel, Google Sheets, and most spreadsheet applications. You can also sync Libraries directly with Google Sheets.

Memento offers powerful search functionality across all Libraries or within a single Library. You can search by keywords, scan barcodes to find matching entries, or create custom filters based on any field criteria.

Yes. You can select multiple entries and perform batch operations like editing, deleting, exporting, or sending data.

Yes. Memento supports CSV format for both import and export, which is compatible with Excel, Google Sheets, and most database applications. You can also export individual entries as PDF. On Android, Pro users can export to Google Docs.

Memento offers multiple view modes: List (default scrolling view), Table (spreadsheet-like grid), Cards (visual card layout), Map (for entries with location data), and Calendar (for entries with date/time fields).

You can create custom filters based on any field criteria and save them for quick access. Sorting can be configured by any field in ascending or descending order. Grouping allows you to organize entries into categories.

Aggregations perform mathematical operations (sum, average, minimum, maximum) across all entries or within groups. For example, you can calculate total expenses, average ratings, or highest/lowest values.

Yes. Memento includes charting functionality to visualize your data with various chart types. You can also export data to PDF or CSV for external reporting.

Yes, Memento includes a library of pre-built templates for common use cases like inventory management, contacts, expenses, tasks, collections, and more. You can use these templates as-is or customize them to fit your specific needs. You can also create your own templates and share them with the community.

Yes. Memento Cloud allows real-time synchronization across devices and team members. You can invite users, create user groups, and set granular permissions.

Memento offers flexible access control at multiple levels: Library access (who can view/edit), field-level permissions (hiding sensitive data from certain users), and Web Form access (public, password-protected, or user-restricted).

Yes. Memento tracks the creation and modification history for each entry, including timestamps and the username of who made changes. You can also view a complete history of modifications.

You can export a Library template (structure only) and share it with others or contribute it to the online catalog. Others can then import this template and add their own data.

Yes. Web Forms allow you to collect data from customers, partners, or team members who don't have Memento accounts. You control which fields they can fill and how they access the form.

Memento Cloud stores your Libraries online and synchronizes them across all your devices. Any changes made on one device automatically sync to others, ensuring you always have the latest data. Memento Cloud is powered by Google Cloud, providing enterprise-grade infrastructure and security.

Yes. Mobile versions (Android and iOS) work fully offline. Changes made offline will sync to the cloud automatically once you're connected to the internet. Desktop versions require an internet connection to access cloud libraries.

Yes. All data transmitted to and from Memento Cloud is encrypted using industry-standard SSL/TLS protocols. Data at rest is also encrypted on Google Cloud servers. Additionally, you can create encrypted libraries on Android for extra protection, securing sensitive data with a password using AES-256 encryption.

Yes. On Android with a Pro subscription or higher, you can synchronize libraries with Google Sheets. This allows bidirectional sync - changes in Memento appear in Sheets and vice versa. Free and Lite users can sync up to 2 libraries with Google Sheets. You can also optionally upload attached files to Google Drive.

You'll need to upgrade your subscription plan to get additional storage. You can also delete old entries or optimize attached files to reduce storage usage.

Triggers execute automatically when specific events occur (like creating or editing an entry), while Actions run when you click a button. Both can be created in two ways: using Automation Rules (no-code visual blocks) or Scripts (JavaScript code) for advanced customization.

No. Most automation can be achieved using Automation Rules - a no-code feature where you build rules from visual blocks without any programming. Scripts (JavaScript) are only needed for advanced custom logic. To write Scripts, you need basic JavaScript knowledge, but many users never need them thanks to Automation Rules.

Yes. Use Calculation fields for simple math and logic, or JavaScript fields for complex operations. Both automatically update when related fields change.

Dependencies allow fields to show, hide, or change their options based on values in other fields. For example, a "Model" dropdown can show different options depending on which "Brand" is selected.

Yes. The Autofill feature connects to external databases (books, movies, music, products) and automatically fills fields when you enter a title or scan a barcode. Advanced users can also create custom JavaScript data sources to fetch data from any external API or web service.

Yes! Memento integrates with Zapier, allowing you to connect with thousands of apps like Google Sheets, Airtable, Slack, Trello, and more. The Memento Cloud API enables custom integrations for developers.

The key advantage of Memento is that you can create a custom app tailored to your unique needs that you can't find elsewhere. Common personal uses include task lists, habit tracking, budgeting, shopping lists, recipes, book/movie/music collections, travel planning, health records, study notes, home inventory, and contact management - but the possibilities are limitless.

Business uses include inventory management, CRM, project management, employee records, production tracking, asset management, product catalogs, sales tracking, expense management, and creating custom ERP systems.

Yes. Memento's flexibility allows it to replace many single-purpose apps by creating custom databases tailored to your specific needs, all in one application.

Yes. Small businesses can build affordable custom management systems without expensive enterprise software. The team collaboration features and Web Forms make it ideal for small teams.

Memento Database is available on Android, iOS (iPhone and iPad), Windows, macOS, and Linux. All your data syncs seamlessly across all platforms through Memento Cloud.

Yes. Advanced users can write SQL SELECT queries to retrieve and analyze data for complex reports. Currently, only read operations (SELECT) are supported - data modification queries (INSERT, UPDATE, DELETE) are not available yet.

Memento supports CSV format for both import and export, which is compatible with Excel, Google Sheets, and most database applications. You can also export individual entries as PDF.

Limits depend on your subscription plan, primarily based on cloud storage space. There are no artificial limits on the number of Libraries or entries you can create locally on mobile devices.
